Microsoft to make its own tablet called Surface, puts Windows RT centre stage

Microsoft has announced its own tablet, called Surface, for “work and play”, said CEO Steve Ballmer at an event in Los Angeles yesterday.

The first of what will be a family of devices has a 10.6” Corning Gorilla Glass screen, is just 9.3mm thick, and has a magnesium “VaporMg” case with a built-in stand/magnetic cover which doubles as a multitouch keyboard.

Surface comes in two forms. One runs Windows RT with an NVidia processor, which means it is the ARM version of Windows 8. There is a desktop UI alongside Metro, but the desktop is there only to run Microsoft Office (which is bundled), Explorer, and whatever other utilities Microsoft chooses to include. It is not possible to install new desktop applications. Users can only install Metro-style apps from the Windows Store.

The other runs Windows 8 Professional. Note that this x86 version is heavier (903g vs 676g), thicker (13.5mm vs 9.3mm) and more power-hungry (42 W-h vs 31.5 W-h). However, it does benefit from USB 3.0 rather than USB 2.0.

Why has Microsoft done this, and risked alienating the hardware partners on which it depends for the success of Windows?

I posted on this subject a few days ago. Yes, Microsoft’s hardware partners have driven the success of Windows, but they have also been part of the problem as Apple has captured a gradually increasing proportion of the personal computer market. Problems include foistware(unwanted software) bundled with PCs and rushed designs that have too many annoyances.

With Windows Phone 7, it was not until Nokia entered the market a year after the launch that we saw hardware and design quality that does justice to the operating system. Distracted by Android, partners like HTC and Samsung brought out drab, unimaginative phones that contributed to a poor start for Microsoft’s smartphone OS.

Now with Windows 8, the danger is that the same may happen again. We have seen few Windows RT designs, and evidence that vendors are having difficulty in reimagining Windows.

Until today, that is. The announcement ensures that Windows RT will win plenty of attention at launch, alongside the x86 editions, and that Microsoft has a measure of control over its own destiny, in how Windows 8 is realised in hardware.

Microsoft says that the Windows RT Surface will launch at the same time as Windows 8, but that the Intel edition will follow a few months later.

How much for a Surface? The press release says:

Suggested retail pricing will be announced closer to availability and is expected to be competitive with a comparable ARM tablet or Intel Ultrabook-class PC. OEMs will have cost and feature parity on Windows 8 and Windows RT.

Close up with Asus PadFone: is a converged device in your future?

Asus held an event in London to show off the devices it revealed at Computex in Taipei recently, though sadly there was no Windows RT device to be seen.

Among the Zenbook Ultrabooks and Transformer Primes there was something innovative though, which was a near-final sample of the PadFone, which combines smartphone, tablet and Android laptop into one package.

The thinking is simple: why have an expensive smartphone as well as an expensive tablet, each perhaps with its own SIM card and contract, when the smartphone can power both? In the PadFone, the phone docks into the tablet, and the tablet clips into a keyboard case. As a final flourish, there is an optional headset stylus, a stylus with a Bluetooth headset built-in so you can answer the phone easily when it is docked.

Here are the three main pieces:

image

The tablet, note, is useless until you dock the phone. You do this by opening a flap on the back and dropping it in.

image

The tablet then works just like any other Android tablet, though it is heavier than average, and has a bulbous section on the underside.

Attach to the keyboard case, and you have a laptop.

image

The tablet has a 10.1”, 1280 x 800 screen with Gorilla Glass, a speaker and headphone jack, and a front-facing camera.

The phone has 1GB RAM, 16GB flash storage plus Micro-SD support, Qualcomm 8260A Snapdragon S4 Dual-core processor with Andreno 225 GPU, rear camera and its own front-facing camera, and runs Android ICS.

The keyboard adds USB ports and a card reader.

Each device has its own battery so a full setup has three batteries, or  four if you count one in the stylus headset. However you can have scenarios where the tablet is out of power but the phone is not, for example, which would be annoying.

I spent some time with the PadFone, scribbling on the excellent note-taking app which comes with it, and assembling and disassembling the unit to get a feel for how it works. There is plenty to like. The phone itself looks great and seems fast and capable. Docking and removing it is straightforward, particularly since the flap acts as a lever to eject the phone gently. Asus assured me that it has been tested for thousands of insertions. The tablet worked well too, though it is heavier than most and the protrusion which holds the smartphone is inelegant.

A winner then? I am not sure. It is interesting and innovative, but the mechanics need some refinement. Most people have a case to protect their smartphones, but for the PadFone you will either need to remove the phone from its case when you dock it, or else treat the tablet as the case, in which case it will not slip so easily into a jacket pocket or handbag.

The stylus headset is not just a gimmick; you will need this, or another Bluetooth headset, to make sense of using the phone when it is docked.

Some variations on this theme occur to me. After another generation of miniaturisation, perhaps you could design a phone so slim that it fits into the case more like an old PCMCIA card used to slot into a laptop, without an ugly protruding flap? Another idea would be to make all the communication between phone and tablet wireless, building just enough smarts into the tablet that it works as a kind of remote desktop into your phone.

The Asus folk present told me that the PadFone is first-generation and we can expect the concept to evolve. Another goal is to make a splash in the smartphone market, using the PadFone as differentiation from all the other Android devices out there.

Apparently the PadFone will normally be sold on contract, and while it will be bundled with the tablet, whose name is the PadFone Station, the keyboard and stylus headset will be optional extras.

BlackBerry 10: QNX multitasking goodness

I attended the London BlackBerry Jam, one of around 500 developers (the event was sold out) who showed up to learn about developing for Blackberry 10 and in the hope of snagging a prototype of RIM’s next smartphone, the BlackBerry 10 Dev Alpha. The event is part of a tour of 26 cities worldwide. I also spoke to Vivek Bhardwaj, Head of Software Portfolio EMEA for RIM. Does BlackBerry 10 have what it takes to  compete against Apple iPhone and Google Android?

A few quick observations. The event was split into native and web tracks, with the native track focusing on  C/C++ development and the Cascades UI framework, and the web track covering WebWorks, the HTML 5 developer tools which you can use to target mobiles as far back as BlackBerry 5, or to create apps that share code between BlackBerry and other mobile platforms.

There was also a tour of various mobile JavaScript libraries. One that caught my attention was Zepto.js, which implements most of the jQuery API in just 8.4k of compressed code, around 25% of the size of jQuery. The trade-off, aside from some missing features, is lack of support for Internet Explorer, though support for IE 10 is under consideration. Thought-provoking: the price of legacy platforms?

It turned out that the device Bhardwaj was holding, though pretty much the same hardware as the Dev Alpha giveaway, was more revealing as a glimpse of the next-generation BlackBerry. The Dev Alpha, which has an impressive 1280 x 768 screen, comes with no applications other than the web browser and its user interface is pretty much that of the PlayBook. Bhardwaj’s demo device on the other hand is a complete early version of BlackBerry 10 though there were parts that he would not demonstrate. I went to compose an email and he said, “we are not ready to show that yet.”

image

So what is distinctive about BlackBerry 10? One of its key features is multitasking, thanks to the processor scheduling capabilities of QNX, the embedded operating system which underlies both PlayBook and BlackBerry 10. According to Bhardwaj, this enables up to 8 apps to run at once. “Applications all run simultaneously. We don’t need to pause them,” he said. “It’s much more about flow.”

Although apps do run full screen, you can take advantage of the multitasking by “peeking” at a background app. This means holding your finger towards the corner of an app and dragging it left to see a little of what is underneath. In the pic below this is another image.

image

Talking to developers at the event I picked up considerable enthusiasm for BlackBerry 10, though compatibility is a headache. If your customer asks you to support all versions of BlackBerry back to the 5.0 series, you are stuck with WebWorks and the pre-WebKit browser in 5.0. If you can convince your customer to forget 5.0, then you can develop for WebKit. If you want to use Cascades then you are restricted to PlayBook and BlackBerry 10.

BlackBerry 10 also supports Adobe AIR, for Flash-based apps, and an Android runtime for repackaged Android apps.

The prototype BlackBerry 10 phone looks good, but as a brand new platform is it sufficiently exciting to revive RIM’s fortunes? “I don’t believe that in a trillion-dollar plus industry there can only be two players. I think there is more than enough space for four or five platforms. It’s very short-sighted if we think there can only be three ecosystems,” said Bhardwaj.  

Three reasons why Microsoft should make its own Windows RT (ARM) Tablet

Rumours are flying that Microsoft will announce an own-brand Windows RT tablet on Monday.

No comment on the truth of these, but it would be a smart move.

Here are three reasons.

First, the OEM foistware problem. This has got a little better in recent years, but not enough to compete with Apple and its clean machines. The problem is so bad that Microsoft set up its own retail stores to sell  cleaned-up Windows PCs:

Many new PCs come filled with lots of trialware and sample software that slows your computer down—removing all that is a pain, so we do it for you! Every PC the Microsoft Store sells is put on a software diet and performance is tuned to run the best it can.

Microsoft addressed this in Windows Phone by imposing conditions on the extent to which OEMs can customise the user interface or embed their own software. It cannot do this  though with Windows 8 on x86. Manufacturing its own model is one of the few ways Microsoft can get Windows PCs that work as designed into the hands of consumers.

Second, the design problem. Few Windows PCs (if any) are as well designed as Macs or iPads. Manufacturers are geared towards low prices and frequent model changes rather than intensive work on every detail of the design.

Third, Microsoft wants to make a splash with Windows RT, the ARM version, and there is evidence that it is having difficulty communicating its benefits or convincing its OEM partners to get fully behind it.

This third is the biggest issue, which might drive Microsoft to compete with its third-party partners, and requires some explanation. Many people I speak to cannot see the point of Windows RT. This version of Windows 8 will not run x86 applications, so you cannot install any of your old software. Further, there is no way to install desktop applications, so software vendors cannot port their existing applications. They must create new Metro-style apps instead. So why bother with Windows RT?

This reaction is understandable, but unfortunately for Microsoft Windows 8 on x86 has no chance of competing with Apple’s iPad.

Yesterday I attended an Asus event in London where the company was showing its new range of Android tablets and Windows ultrabooks. It was not showing its prototype Windows 8 machines, but I was able to discuss the likely Windows 8 products, All but one is x86, and they will have Wacom digitizers,  which means they will work with a stylus like an old-style Tablet PC, as well as with touch. That will push up the price.

Worse still, these x86 devices, like the Samsung Slate on which I run WIndows 8 Release Preview, will not be enjoyable to use with touch alone. Users will find themselves running applications designed for keyboard and mouse: you can get them to work, but it is frustrating. These devices are not Windows reimagined, they are the old Windows plus a few new tricks.

Too expensive, too hard to use: Windows 8 on x86 is not an iPad-beater.

Windows RT on the other hand is more promising. This does have a desktop, but it will only run Office, Windows Explorer, and whatever other desktop utilities Microsoft chooses to provide. Office aside, you will be forced to use touch-friendly Metro apps most of the time. Microsoft can tune Windows RT by removing legacy components that are no longer needed, because applications which rely on them cannot be installed. You also get the power efficiency of ARM, so a long battery life. Finally, if Microsoft has done it right Windows RT should be more secure, since the entire operating system is locked down.

Windows RT is critical to Microsoft and if it has to make its own hardware in order to market it properly, then it should do so.

Microsoft, Windows 8, and the Innovator’s Dilemma (or, why you hate Windows 8)

One thing is obvious from the immediate reaction to Windows 8 Release Preview. Most of those who try it do not like it. It is a contrast to the pre-release days of Windows 7, when there was near-consensus that, whatever you think of Windows overall, the new edition was better than its predecessors.

Why would a company with huge resources and the world’s most popular desktop operating system – 600 million Windows 7 licenses so far, according to OEM VP Steven Guggenheimer – create a new edition which its customers do not want?

Microsoft under Steve Ballmer is a somewhat dysfunctional company – too many meetings, says ex-softie Brandon Watson – but there is still a wealth of talent there. Specifically, Windows President Steven Sinofsky has proven his ability, first with Microsoft Office 2007 which beat off the challenge from OpenOffice.org, and next with Windows 7, which if it repeated the disappointment of Windows Vista would have damaged the company severely.

If it is not incompetence, then, what is it?

In this context, Clayton M. Christensen’s 1997 classic The Innovator’s Dilemma – When new technologies cause great firms to fail is a good read. Chapter one is here. Christensen studied the hard drive market, asking why sixteen of the seventeen companies which dominated the industry in 1976 had failed or been acquired by 1995, replaced by new entrants to the market. Christensen argues that these firms failed because they listened too much to their customers. He says that delivering what your customers want is mostly a good idea, but occasionally fatal:

This is one of the innovator’s dilemmas: Blindly following the maxim that good managers should keep close to their customers can sometimes be a fatal mistake.

Specifically, hard drive companies failed because new entrants had physically smaller hard drives that were more popular. The reason the established companies failed was because their customers had told them that physically smaller drives was not what they wanted:

Why were the leading drive makers unable to launch 8-inch drives until it was too late? Clearly, they were technologically capable of producing these drives. Their failure resulted from delay in making the strategic commitment to enter the emerging market in which the 8-inch drives initially could be sold. Interviews with marketing and engineering executives close to these companies suggest that the established 14-inch drive manufacturers were held captive by customers. Mainframe computer manufacturers did not need an 8-inch drive. In fact, they explicitly did not want it: they wanted drives with increased capacity at a lower cost per megabyte. The 14-inch drive manufacturers were listening and responding to their established customers. And their customers–in a way that was not apparent to either the disk drive manufacturers or their computer-making customers–were pulling them along a trajectory of 22 percent capacity growth in a 14-inch platform that would ultimately prove fatal.

Are there any parallels with what is happening in computer operating systems today? I think there are. It is not exact, given that tablet pioneer Apple cannot be described as a new entrant, though Google with Android is a closer match. Nevertheless, there is a new kind of operating system based on mobility, touch control, long battery life, secure store-delivered apps, and cloud connectivity, which is eating into the market share for Windows. Further, it seems to me that for Microsoft to do the kind of new Windows that its customers are asking for, which Christensen calls a “sustaining innovation”, like Windows 7 but faster, more reliable, more secure, and with new features that make it easier to use and more capable, would be a trajectory of death. Existing customers would praise it and be more likely to upgrade, but it would do nothing to stem the market share bleed to Apple iPad and the like. Nor would it advance Microsoft’s position in smartphones.

Should Microsoft have adapted its Windows Phone OS for tablets two years ago, or created Metro-style Windows as an independent OS while maintaining Windows desktop separately? YES say customers infuriated by the full-screen Start menu. Yet, the dismal sales for Windows Phone show how difficult it is to enter a market where competitors are firmly entrenched. Would not the same apply to Windows Metro? Reviewers might like it, developers might like it, but in the shops customers would still prefer the safety of iPad and Android and their vast range of available apps.

You begin to see the remorseless logic behind Windows 8, which binds new and old so tightly that you cannot escape either. Don’t like it? Stick with Windows 7.

Microsoft will not say this, but my guess is that customer dissatisfaction with Windows 8 is expected. It is the cost, a heavy cost, of the fight to be a part of the next generation of client computers. It is noticeable though that while the feedback from users is mostly hostile, Microsoft’s OEM partners are right behind it. They do not like seeing their business munched by Apple.

The above does not prove that Microsoft is doing the right thing. Displeasing your customers, remember, is mostly the wrong thing to do. Windows 8 may fail, and Microsoft, already a company with shrinking influence, may go into an unstoppable decline. Bill Gates was right about the tablet taking over from the laptop, history may say, but Microsoft was incapable of making the radical changes to Windows that would make it work until it was too late.

Give credit for this though: Windows 8 is a bold move, and unlike the Tablet PCs that Gates waved around ten years ago, it is an OS that is fit for purpose. Sinofsky’s goal is to unify the smartphone and the tablet, making a new mobile OS that users will enjoy while also maintaining the legacy desktop and slotting in to enterprise management infrastructure. I admire his tenacity in the face of intense protest, and I am beginning to understand that foresight rather than stupidity underlies his efforts.

Microsoft announces Internet Explorer for Xbox 360, makes bid for living room

At the E3 conference in Las Vegas Microsoft has made a series of announcements focused on its Xbox 360 games console, but also relating to Windows Phone, Windows 8, and even Apple iOS and Google Android.

image

Xbox SmartGlass is a free app for Windows Phone, Windows 8, iOS and Android which links communicates with the Xbox. Examples include:

  • Watching a movie on a tablet while travelling, getting half way through, and automatically resuming on the Xbox at home.
  • Seeing related content on your tablet such as team members, maps, game inventory, and so on, while the TV or game action takes place on the main Xbox screen.
  • Using the tablet to navigate web pages that are also displayed in Internet Explorer on the Xbox, tapping links and using pinch and zoom.

image

Yes, IE is now promised for the Xbox “this fall”, and there will be a new web hub. No word yet about Adobe Flash, but with a strong focus on multimedia in this context, it would certainly make sense to include it, as Microsoft has done for Metro-style IE in Windows 8. In fact, the browser shown at E3 on Xbox looked reminiscent of the Windows 8 Metro version.

Other major consoles also have web browsers, so what is special about Microsoft’s late inclusion of the same feature? The company says that web browsers on other consoles are little used because they are hard to navigate, and is counting on a combination of Kinect voice control and SmartGlass to make it work better on Xbox.

Another problem though is that most web sites are simply not designed for viewing from twelve feet back. A second awkward question: if you have your tablet out, why not just use the tablet’s own web browser?

It makes little sense for general web browsing, but can work for playing videos or viewing images, which I guess is the main idea here.

Microsoft has also announced Xbox Music, which sounds like a replacement for Zune and its subscriptions. You will be able to download and/or subscribe to 30 million tracks, and the service will work seamlessly, according to Microsoft, on Windows Phone, Xbox and Windows 8.

Watching the E3 press event was an odd experience. Xbox games are still dominated by macho fighting titles like Halo, Splinter Cell, and Black Ops, all of which were demonstrated complete with bone-crunching violence, death and mayhem. At the same time, Microsoft is trying to make the console the entertainment hub for the whole family, and for movies and sport as much as for games, so we also got Dance Central 3, and exercising with Nike plus Kinect.

One thing not mentioned was Xbox vNext. The 360 was released in November 2005, an eternity ago in technology terms. The hardware has held up well, but even so, if Apple pulls out something TV-related soon (perhaps even at its WWDC event next week) then it will have the advantage of being able to release something based on up to date hardware.

Getting started with Windows 8: Four things new users need to know

Today I upgraded a laptop from Windows 7 to Windows 8 Release Preview and watched the owner’s first steps with the new operating system – a bit like the Chris (or Joe) Pirillo experiment, except this was an in-place upgrade so a somewhat familiar environment.

Nevertheless, the user struggled to get going. Microsoft could (and I hope will) make this easier by spelling out the use of four simple features which are needed in order to navigate and control Windows 8 successfully.

Note: this is for users with keyboard and mouse. If you have a touch screen or even a new laptop with a trackpad designed for Windows 8, it is easier.

1. How to open the Start menu. There are several ways:

a) Move the mouse down to the bottom left corner or just beyond. A Start button appears.

image

b) Move the mouse down to the bottom right corner or just beyond (tablet users swipe from the right edge). The Charms bar appears and you can click Start.

image

c) Press the Windows key, or Ctrl-Esc if you do not have one. Seems obvious; but my victim did not think to do so. It appears that the Windows key is not that popular with users.

2. How do you close or exit a Metro-style app? Easy – see above – bring up the Start menu. This is not obvious though. My user instinctively pressed Esc, which did not work.

3. How do you control a Metro-style app? There are two key things to learn:

a) Right-click the mouse (swipe up on a tablet) to summon app menus and controls. For example, in the Music app this gets you play controls.

image

b) Mouse to bottom right corner or just beyond and click Settings. In Windows 8 the Settings on the Charms bar are dynamic. App settings appear here. For example, in the Music app you can get at your account settings and other preferences, or even change the volume.

image

4) How do you switch between apps? Answer: Alt-tab is your friend. This is the most reliable way to see all running desktop and Metro-style apps and switch between them.

Another thing to try is to move the mouse to the top left corner or just beyond until a thumbnail appears, then drag down. Touch users swipe from the left and immediately back out. This shows thumbnails of running Metro-style apps, plus one for the desktop. Right-click a thumbnail for options including Close.

image

There are a couple of problems with this feature. First, the gesture or mouse movement is not obvious. Second, it does not show all running apps, since the desktop shows as a single thumbnail.

The big question: how will Microsoft get users past the initial hump of not finding the Start menu or other essentials? I have seen even highly technical users slip up. for example someone who thought Metro-style Mail was broken because it opened as a mainly blank screen with the word Mail and no obvious way to get it working. The solution is Charms and then Settings, but this kind of problem is frustrating.

A human guide is ideal, but failing that what can Microsoft do? Users often ignore introductory tutorials, so I would suggest on-screen help like pointing arrows for those critical first minutes.

The deeper question: are these problems a sign of something wrong in the Windows 8 design, or is it to be expected when radical changes are made to a familiar system? My instinct is that Microsoft could have done more to make it discoverable, but I do not see it as a showstopper. Users will learn.

Review: Cygnett Bluetooth Keyboard for iPad, Windows

In the iPad era there is increasing demand for wireless keyboards that will transform your tablet into a productive writing machine. I have tried a number of such gadgets recently, including a bargain-price iPad keyboard case and an expensive Samsung keyboard to go with the Slate I have been using for Windows 8 Consumer Preview.

Both keyboards work, but with so many annoyances that I rarely use them. The keyboard case works well enough, if you can cope with squishy keys and a tiny power switch, but adds so much weight and bulk to the iPad that it becomes like a laptop, and in doing so loses much of its appeal. The Samsung keyboard on the other hand has a quality feel but lacks a proper power switch, and I found the only way to prevent it powering up when in your bag is to remove the batteries, which is a nuisance. Further, there is some kind of design fault with the keys which can get stuck down; they pop back easily enough, but after a few times something snaps and I now have a key that slopes slightly.

Enter the Cygnett Bluetooth Keyboard, primarily designed for the iPad but which works find with the Slate and no doubt numerous other devices, and which is priced competitively considering it has hard keys and is rechargeable.

image

I found several things to like.

First, it has a real on/off switch on the back, something I value having experienced problems with Samsung’s soft power key.

Second, it is small, and will fit in the the top inside pocket of a man’s jacket or tucked into a flap in almost any bag or case. The longest side of the keypad is around 1.5cm less than the length of the iPad itself.

Third, it seems robust and the keys are pleasantly responsive.

image

Getting started was simple enough. Charge it using the supplied USB connector, and pair with the iPad or other device by depressing the recessed pairing key, scanning for new devices, and typing the code given.

I find I can get a good speed on this device, though it is a little cramped especially if you do true touch typing using all your fingers. Still, this is mainly a matter of practice and it is a big step up, for me, from the soft keyboard on an iPad or tablet. Another reason to prefer a physical keyboard is that you get twice as much screen space to view your document.

The keypad also works fine with my Windows 8 Slate, though it has Mac-style keys so no Windows key. Of course you can use Ctrl-Esc for this. There is a Print Screen key though, so from my point of view all the important keys are covered. There is no right Shift key.

One small disappointment: although it has a mini USB socket for charging, this keypad is wireless only. It will not work as a USB keyboard even if you use a full USB cable, rather than the charge-only cable supplied. A shame, because there are circumstances when a USB keyboard is useful, such as for changing BIOS settings on a Windows tablet.

The keypad also works with some Android devices. However I was unable to pair it with an HTC Desire smartphone, and I have seen reports of similar issues with other Android mobile devices. If the device prompts for a number to type on the keyboard, you are in business. If it suggests typing a generic code such as 0000 on the device, it does not work, though there may be a workaround of which I am not aware.

Another limitation: you can only pair the keypad with one device at a time.

Nevertheless, I like this keypad better than the Samsung keyboard which cost much more. Recommended.

 

NVIDIA’s GPU in the cloud: will you still want an Xbox or PlayStation?

NVIDIA’s GPU Technology conference is an unusual event, in part a get-together for academic researchers using HPC, in part a marketing pitch for the company. The focus of the event is on GPU computing, in other words using the GPU for purposes other than driving a display, such as processing simulations to model climate change or fluid dynamics, or to process huge amounts of data in order to calculate where best to drill for oil. However NVIDIA also uses the event to announce its latest GPU innovations, and CEO Jen-Hsun Huang used this morning’s keynote to introduce its GPU in the cloud initiative.

This takes two forms, though both are based on a feature of the new “Kepler” wave of NVIDIA GPUs which allows them to render graphics to a stream rather than to a display. It is the world’s first virtualized GPU, he claimed.

image

The first target is enterprise VDI (Virtual Desktop Infrastructure). The idea is that in the era of BYOD (Bring Your Own Device) there is high demand for the ability to run Windows applications on devices of every kind, perhaps especially Apple iPads. This works fine via virtualisation for everyday applications, but what about GPU-intensive applications such as Autocad or Adobe Photoshop? Using a Kepler GPU you can run up to 100 virtual desktop instances with GPU acceleration. NVIDIA calls this the VGX Platform.

image

What actually gets sent to the client is mostly H.264 video, which means most current devices have good support, though of course you still need a remote desktop client.

The second target is game streaming. The key problem here – provided you have enough bandwidth – is minimising the lag between when a player moves or clicks Fire, and when the video responds. NVIDIA has developed software called the Geforce GRID which it will supply along with specially adapted Kepler GPUs to cloud companies such as Gaikai. Using the Geforce GRID, lag is reduced, according to NVIDIA, to something close to what you would get from a game console.

image

We saw a demo of a new Mech shooter game in which one player is using an Asus Transformer Prime, an Android tablet, and the other an LG television which has a streaming client built in. The game is rendered in the cloud but streamed to the clients with low latency.

image

“This is your game console,” said NVIDIA CEO Jen-Sun Huang, holding the Ethernet cable that connected the TV to the internet.

image

The concept is attractive for all sorts of reasons. Users can play games without having to download and install, or connect instantly to a game being played by a friend. Game companies are protected from piracy, because the game code runs in the cloud, not on the device.

NVIDIA does not plan to run its own cloud services, but is working with partners, as the following slide illustrates. On the VDI side, Citrix, Microsoft, VMWare and Xen were mentioned as partners.

image

If cloud GPU systems take off, will it cannibalise the market for powerful GPUs in client devices, whether PCs, game consoles or tablets? I put this to Huang in the press Q&A after the keynote, and he denied it, saying that people like designers hate to share their PCs. It was an odd and unsatisfactory answer. After all, if Huang is saying that your games console is now an Ethernet cable, he is also saying that there is no need any longer for game consoles which contain powerful NVIDIA GPUs. The same might apply to professional workstations, with the logic that cloud computing always presents: that shared resources have better utilisation and therefore lower cost.

Review: Kingston 240GB V+200 ssdNow SSD kit

Prices for SSDs (solid-state drives) are falling and capacity is rising, so much so that fitting one now looks eminently sensible if you value performance and can manage with a bit less space than a hard drive offers – though note that you should really run Windows 7, or on the Mac OSX Snow Leopard or later, as these operating systems support SSD TRIM, improving performance by telling the drive which blocks of data are no longer in use and can be safely deleted.

The primary benefit of SSD is performance, but you also get silent running and lower power consumption.

image

This Kingston kit is a generous bundle, suitable for converting a laptop or desktop. It includes a USB-powered external disk caddy which assists with the transfer of your existing data as well as enabling you to continue using your old laptop drive for external storage if you wish. There are also brackets and cables so you can fit the drive into a desktop PC, and a CD containing an Acronis disk clone tool.

The recommended method for installation depends on whether you are upgrading a laptop or a desktop.  The first step is the same for both and may be the hardest: reduce the size of the data on your existing drive to less than 240GB. Next, if you are on a laptop, you remove the existing drive install the SSD, fit the existing drive to the caddy and connect it with USB, reboot using the CD, boot into Acronis and clone the existing drive to the SSD.

If you are on a desktop, your existing 3.5” drive will not fit into the caddy, so you fit the SSD to the caddy, connect, reboot into Acronis, clone the existing drive to the SSD, and then switch off and replace the existing desktop drive with the SSD using the brackets provided.

For this review I used the former approach but either should work well. On a three-year old laptop running Windows 7 64-bit I was rewarded with a Windows Experience Index for the hard drive of 7.7.

image

However, this laptop only has SATA 2, whereas the drive supports SATA 3 and would work faster if this were available.

Kingston quotes 480 MB/s for sequential writes and power consumption of 0.565w idle rising to 2.065w for writes.

If you do not need the kit you can get the SSD a little cheaper on its own.

An excellent kit though, and the Acronis cloning solution is cleaner than others I have seen which require software to be installed in Windows.
