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.

A vending machine with a difference: this one buys your old phone

I`m visiting San Jose and looked into the Valley Fair shopping mall. I was intrigued to see an inverse vending machine, one that buys your old phone or other gadgets.

image

You tap the screen to start the sale or get a valuation. Then you pop your old phone into the receptacle and the machine checks it out, using “Advanced machine vision and artificial intelligence” to work out what you have put in. You have power up your device for a second stage evaluation, presumably to check whether it actually works. Finally, you get paid in cash or credit, with an option to donate to charity.

The EcoATM machine will take anything, though some devices have zero value in which case you have only the warm glow of satisfaction that comes from recycling.

I was offered up to $104 for my 8GB Apple iPhone 4, though it was a valuation only since the machine was sadly not fully working. Of course you could do better on eBay, but instant cash and no hassle has its attractions.

OK, so what if you grab someone else’s phone, throw it into the machine, and walk away with the cash? The makers claim to have all sorts of anti-theft measures, including video of you doing the deed, though conceptually the idea does seem vulnerable to abuse.

These machines are USA only at the moment, though an international roll-out is planned.

Whoosh! Review: Samsung 830 series SSD kit

Is it worth replacing your laptop’s hard drive with a solid state drive instead? If you can put up with a few limitations (and perhaps a smaller drive) then it probably is. SSD is faster than a spinning disk, and you will notice this in the form of faster boot, faster application loading, and a snappier system in general. Battery life may improve too.

This review covers the Samsung 830 series 128GB SSD, specifically the laptop installation kit which contains all you need (except the screwdriver).

image

Laptop drives are usually easy to replace physically, but migrating your operating system can be tricky. Samsung seems to be making an effort to simplify this, though it could do better. The essentials are here though, particularly a very handy cable that lets you connect your new SSD as an external USB drive. This means you can image your existing drive to the SSD, then replace the drive and boot as normal. The package also includes two CDs, one for Norton Ghost and the other for some utilities and documentation. Finally there is a short printed manual and of course the drive itself. Since it is thinner than a hard drive, a spacer is supplied which bulks it out to the size of a standard 2.5” drive if necessary.

image

The laptop I picked for this test is a Dell running Windows 7 64-bit. It has a 160GB 7200 rpm Seagate drive – typical of a laptop which is a few years old.

Curiously, although all the kit is supplied to migrate from your existing hard drive, there is a note in the instruction leaflet that says “Samsung recommends that you do a fresh OS install to ensure an optimal operating environment for your new SSD”. Good advice, except that laptops usually do not come with Windows install media, and if they do it is recovery media with recreates the original install, which is not quite the same as a fresh install. Another problem with a fresh install is the time-consuming job of reinstalling your applications. There are many advantages to migration rather than clean install, even if the final result is not optimal. You can also tweak an existing Windows install for SSD so it is not that bad.

A problem with this kit is that although it does have all you need, it lacks a simple step by step guide. That is not for want of trying; someone has worked hard on the interactive manual on one of the CDs. Even so, with a printed manual that covers both desktop and laptop versions of the kit, two CDs, Samsung’s Magician utility as well as Norton Ghost, it ends up being a confusing bundle.

Most laptops only have one drive, and you may well find that there is more data on your current drive than there is space on the new SSD. I recall a note somewhere that advises you to delete unimportant data to make space. Alternatively, you could get Samsung’s 256GB kit for around twice the price. On a desktop, you would likely use an SSD drive for booting and for the operating system, but conventional hard drives for data.

Norton Ghost is not my favourite disk utility. It is a backup tool as well as a drive cloning utility, and has a rather complex and intrusive install. An alternative is to use the backup and restore built into Windows 7, which would work fine for this although you will need an additional external drive as well as a Windows restore CD or bootable USB device. There are also leaner tools such as Drive Snapshot which work well.

Still, for this review I decided to use the tools in the bundle and installed Norton Ghost. The Ghost install flashed many command prompts at me and then hung for ages doing apparently nothing. I gave up, tried to cancel the installation without success, and rebooted to find that the install had apparently succeeded. I did not trust it so did a repair install which did complete, giving me reasonable confidence that I had Ghost installed OK.

If you go the Ghost route, you should read the document called NortonGhost_Data_Migration_User_Manual_(English).pdf which is in the MagicianSoftware folder on the Samsung Magician CD. The main issue is that Windows 7 creates a hidden system partition which you need to copy to the SSD *first*, otherwise Windows 7 will not boot.

I then attached the SSD drive with the supplied USB cable and ran Ghost to copy the partitions. It took around two hours for my 100GB of data.

image

I then switched the drive with the hard drive installed in the laptop. This was pretty easy, though I did need the supplied spacer in order to press the hard drive close enough to the case for the stubby screws to bite.

Booted up, and Windows warned that it had not been shut down properly. I chose a Normal start, Windows detected the new drive, reconfigured itself, and requested a further restart. That was it.

Well, not quite. I ran Outlook which decided it had to recreate its offline cached mailbox completely. Mine is huge so that took a while.

I also used the Samsung Magician utility to optimize Windows for an SSD install.

image

This utility tweaks a few settings, such as disabling Super Fetch. It also recommends disabling the Windows indexing service. The idea is to reduce the number of disk writes, bearing in mind that SSDs gradually wear and their capacity reduces as data is deleted and written.

There are other Windows tweaks you can make to optimize for SSD. Tom’s hardware has a handy list here. Note that there are trade-offs. Disabling the indexing service may be a good idea for the SSD, but can be inconvenient, particularly if you use Outlook whose search depends on it. Disabling System Restore means you lose its benefit if something in Windows gets corrupted and will have to resort to other restore methods.

Was it worth it? Here are the PassMark before and after results:

  Old 7200 RPM HD New SSD Drive
Disk Mark 234.7 2186.9
Sequential Read 31.4 241.2
Sequential Write 31.2 205.4
Random Seek + RW 2.31 158.2

and here are the results of the PassMark advanced drive test, showing that disk speed improved from 3.7 MB/Sec to 34.8 MB/Sec:

image

A glance tells you all you need to know: the SSD is much faster. The Disk Mark improves by 931%.

In use the laptop feels like a new machine; everything happens faster than before. It is worth the hassle.

    

Nokia gradually fixing Lumia 800, battery life much improved

Nokia has rolled out several updates to its Lumia 800 Windows Phone. The latest is version 1600.2487.8107.12070, which for many users has greatly improved battery life, probably the biggest problem with the phone.

Whether you have this update pushed to you automatically depends on operators, region and who knows what. I followed the unofficial instructions here in order to get the update early and it worked fine for me; but try this at your own risk.

In my case battery life improved from needing to charge daily to running for several days with light use. Results do vary though. You can see how you are doing by running the Nokia diagnostics app and checking battery status.

image

Check the figure for Discharging. If it is 70 mA or less you are doing well. If it is up at 140 mA or higher your phone will not last long on a full charge. Note that for some reason the screen capture utility I use bumped up the battery drain, which on my Lumia hovers around 74 mA since the update.

Some have found that disabling 3G in the “Highest connection speed” setting, under Mobile network substantially extends battery life. Worth a try if you care more about battery life than getting the highest data speeds.

Of course users should not be having these kinds of problems; but despite some hassles – the will not turn on issue is the worst for me but I hope is now fixed – I like the phone increasingly. The feel of the device in your hands is excellent, it is responsive, email works well with Exchange, and the Nokia Drive turn-by-turn directions are proving useful, to mention a few things.

There are still a few annoying bugs. The camera is not as good as it should be, bearing in mind Nokia’s boasting about the Carl Zeiss lens, and a future update may improve the colour balance. There is a volume bug introduced in the latest update, that blasts your ears if a call comes in and your volume is set below 14.

App availability is still limited on Windows Phone. I would like to see a Dropbox client, for example.

Nevertheless, Nokia has created an excellent smartphone and seems to be serious about maintaining and improving it.

The meta-story here is that Microsoft’s success depends on the commitment of its hardware partners. Although Windows Phone was available from others such as HTC and Samsung, who no doubt made a substantial investment, those companies are more committed to Android and that shows in the quality of the devices and the way they are marketed.

Will this story repeat when it comes to Windows 8 tablets, particularly on ARM, which to my mind is the critical platform here?

The best ear buds I have heard: Wolfson’s Digital Silence DS-421D with noise cancellation

At the Mobile World Congress in Barcelona last month I caught up with Wolfson Microelectronics, who make digital converter chips and other audio components. They do not sell many products to end users, but are making an exception for the Digital Silence range of noise-cancelling headsets.

image

The origin of the technology here is in the company’s 2007 acquisition of Sonaptic Ltd, specialists in micro-acoustics, or in other words getting good sound from mobile devices.

The Digital Silence range is unusual among ear buds in including noise cancellation. In other words, microphones on the outside of the buds pick up external sounds, phase reverse them, and add them to the input signal so that you hear more of the music (or voice, if listening to a call) and less of the external sound.

The new Digital Silence range has three models, of which I have been testing the DS-421D, which is set for general availability shortly.

image

What you get is a stereo headset with clip-on controller, spare ear foams, mini-jack adaptors to cope with the fact that some mobiles wire up their 4-pole mini-jacks differently, USB charging cable, and a black zip-up carrying case. As with most headsets, there is also a built-in microphone and answer button. By default they are iPhone-ready, but will work with pretty much any mobile or player with a standard 3.5mm mini-jack output.

The controller has a rechargeable battery, charged by a USB connection, and specified to last for 14 hours of playback. A switch on the controller enables ANC and lights a green LED to show that the battery is OK. The ear buds work without ANC as well, so if the battery gives out you still have music. In a quiet environment, you might also prefer not to use ANC in case it adds artefacts to the sound.

A button on the side of the controller marked Monitor has a dual purpose. Press it to mute the sound; or press and hold to change the ANC filter. There is no display, but the unit plays one, two or three beeps to indicate the selection:

General: 20dB cancellation across a wide frequency band

Aeroplane: Low frequency cancellation such as found in an aeroplane is emphasised.

Office: Speech frequency cancellation around 200Hz – 1kHz is emphasised

Other products in the range are the DS-101A (around £30.00) and the DS-321D (around £50). I do not have a price yet for the DS-421D itself but was told “Under £100”. The DS-101A does not have selectable filters or a call/answer button.

Sound quality

Enough of the technology, how is the sound? This is what counts, and I am impressed. The DS-421D headset sounds excellent even without ANC engaged. No amount of noise cancellation would make them good if they were poor to begin with, and I suspect this fundamental good design is actually more important than the clever processing.

I used a variety of ear-buds for comparison. My regular set are Shure SE210 noise-isolating (not cancelling) ear-buds which I find easily out-perform the ones that come free with smartphones and iPods. I was taken aback by how much better the 421D sounded. The biggest difference is in the bass extension, but the sound is also smoother but without loss of clarity. These are the first ear buds I have used where you do not feel you are compromising by not using over the ear headphones.

The noise cancelling works. Don’t have unrealistic expectations, these will not deliver “digital silence”, but they will substantially reduce the noise. It is a bit like shutting it behind a door. There is also a slight change in the quality of the sound, for the better in my opinion, being a little richer than before. I used the DS-421D on an aeroplane and on the London Underground and had worthwhile results in both cases. I could have the volume lower and still enjoy the music.

I also compared the DS-421D to a set of Sennheiser PXC 300 foldable noise-cancelling headphones. The PXC 300 was slightly more effective in killing background noise, but the reason I tend to leave these at home is that they are bulky and use two AAA batteries which give out if I forget to switch them off. The DS-421D is more convenient. As for sound quality, it is close and I might even give 421D the edge.

The DS-421D is mainly for music, but I found the headset functionality useful too. I used it for Skype on a Windows 8 tablet and it worked much better than using the built-in microphone.

Design

image

The design of the DS-421D  is excellent in terms of technology, but I am not so sure about the ergonomics. The length of cable between the ear buds and the controller is short, so you cannot clip the controller to your belt. It must be on your collar or perhaps top pocket. You could leave it dangling, but it is heavy enough to be a nuisance if you do.

Visually, the design looks a bit geeky to me; not unattractive, but I can imagine the DS-421D losing out among the more fashion-conscious purchasers.

Conclusion

Regular traveller who likes music? I recommend you give these a try. Now you can have noise-cancellation and high quality sound and a small, light headset.

Technical addendum

Wolfson’s noise-cancelling system is called myZone ANC (Ambient Noise Cancellation) which the company says uses “feed-forward, rather than the usual feedback systems”.

What is that then? I hunted around and eventually found Wolfson’s white paper on the subject*. Here is an illustration of feedback versus feed-forward:

image

The figure on the left is a feedback system where the microphone is placed between the loudspeaker and the ear. In the feed-forward system the microphone is external so that the external noise is detected, inverted and added to the input. An advantage is that this does not require a sealed enclosure around the ear.

The main problem with implementation is time-aligning the cancellation signal with the input signal. Wolfson’s solution:

By placing microphones at the rim of the headphone, the ambient noise signal can be acquired and driven to the loudspeaker in advance of its arrival at the eardrum, thus compensating for the intrinsic response time of the loudspeaker.

The illustration in the paper shows a ring array of 5 microphones around each headphone, but since the DS-421D is a small earbud I doubt it has such an array. There is only one visible microphone aperture. Still, this gives some indication of the technology used.

Wolfson did not invent feed-forward as far as I know, so its innovation is in the area of how to achieve accurate time-alignment of the cancellation signal.

*The paper is called Ambient Noise Cancellation for Headphones and Headsets. I cannot find a direct link, but if you go here and search for resources for the WM2002 you will find it.

Images from Mobile World Congress – Huawei’s SmartPhone horse, a Lego robot that collects trash

There are some striking artifacts at Mobile World Congress this year. One is Huawei’s winged horse which stands proudly above one of the fountains.

image

It is made of smartphones, as this close up of a leg shows.

image

Impressive, though it is an expensive way to make a statue and I cannot help being reminded of the anti-capitalist protestors at the gate. Perhaps these are factory rejects.

Another amusing piece is this Lego robot which collects trash and drops it in the bin.

image

Unfortunately I cannot remember what this is promoting!

Ford Microsoft car makes an appearance at Mobile World Congress

At the Showstoppers event just before the Mobile World Congress in Barcelona it was hard to miss the Ford car emblazoned with SYNC Ford Microsoft.

image

So what is this all about? Apparently, the European launch of in-car computers that hook up to Ford’s cloud services. Cue all the jokes about “if your car ran Windows.”

You have to provide the connectivity, for example by docking your smartphone. You can then stream music with voice control, make calls again with voice control, or if you hear a funny noise, send a diagnostic report on your car to Ford or perhaps your dealer.

Why bother with an in-car computer running Windows embedded, when you could just dock a smartphone and let that do all the work? That was my question too, though there are integration benefits. Some details are being held back for an announcement tomorrow.

By the the way if you think the picture is rubbish, blames the Samsung Slate 7, which was used to create this entire post.

Nokia Drive on the Lumia: it works

Over the weekend I took the opportunity to try out Nokia Drive, a turn-by-turn navigation app which comes bundled in the Lumia 800 I have been testing. Well, it was not so much “took the opportunity” as “try anything”, since the Tom Tom the driver was relying on had lost its signal somewhere in the depths of rural England.

I fired up Nokia Drive, entered the destination, and was impressed. It picked up a signal, displayed a well-designed screen stating what was the next turn and how far away, showed our location and progress complete with the road name, and spoke out clear instructions in a voice that was less robotic than some.

image

I was a passenger in this case; how does this work if you are the driver? It turns out that Nokia Drive disables the screen saver (which developers can do with a couple of lines of code – check out UserIdleDetectionMode) so it runs continuously. This is a battery drain, so for longer journeys you will need some sort of car kit; you can get by with just a bracket to hold the phone and a standard micro USB power supply.

For basic navigation this seems to me as good as a Tom Tom though there are a few things missing. You cannot calculate a route offline, it does not show time to destination, and it does not have speed camera warnings.

Nevertheless, a significant benefit for Nokia’s Windows Phone users.

Microsoft puts carriers before users in new Windows Phone update which you might not get

Microsoft has posted a new update for Windows Phone, update 7.10.8107.79. The list of fixes is here, not huge, but including one fix for an issue that has irritated many users:

On-screen keyboard. Fixes an issue to prevent the keyboard from disappearing during typing

But will you get the fix? The real news in Microsoft’s blog post announcing the release is this:

The update, available to all carriers that request it …

Microsoft is also discontinuing its Where’s My Phone update site:

image

Why? Microsoft General Manager Eric Hautala is blaming growth in the number of model, country and carrier variations. That makes the site more work to keep up to date, but no less useful for users.

So what is going on? When Microsoft ditched Windows Mobile for Windows Phone, it sought to learn a lesson from Apple and to provide consistency in user experience, hardware and software. One important part of that is to control updates, so that users do not have to wait for carriers to authorise updates (or not to bother), but get them in a timely manner. This is a potentially a selling point against Android, where users have difficulty getting updates, especially on older devices.

In March last year, Hautala said:

There’s one more thing I want to clear up. I’ve seen a lot of speculation on blogs and forums lately about whether carriers can “block” an update. We work closely with carriers to test and schedule updates. They may ask us for a specific date to start an update. They may ask for updates to be bundled together. But you should ultimately receive all the updates we send out [emphasis mine].

Microsoft now seems to be back-tracking on this commitment, though we need clarification. It is possible that all devices will eventually get the fixes, though not necessarily in this release but in a future roll-up. Check the comments though: users fear the worst.

For background, I recommend you read my piece from February 2010, before the launch of Windows Phone, where Microsoft’s Steve Ballmer, Joe Belfiore and Andy Lees discuss the partner problem.

One further thought: if Microsoft is losing control over its partners, this represents an opportunity for specific partners to make the commitments that Microsoft is backing away from. How about it Nokia?

Update: Microsoft’s Joe Belfiore tweets:

ps – on updates, pls don’t overreact, our focus is on users first! As greg said “nothing has changed” in how we work w carriers on updates.

Greg is Greg Sullivan, Senior Product Manager on Windows Phone.

This still strikes me as a worrying development for users though. The disappearing keyboard bug is troublesome. How can a user find out when they will get the fix? “Ask your carrier” is all very well, but many find carriers unresponsive on this kind of issue.

An Apple iPad Christmas

The Apple iPad had a stunning Christmas – at least, it did in my part of the world.

A key factor was that EA Games decided to offer a range of classic board games adapted as iPad apps for 69p ($0.90)  each. So for less than the cost of a takeaway pizza I downloaded Scrabble, Monopoly, Trivial Pursuit and Risk.

imageimage

The games are not perfect – Scrabble accepts all sorts of odd words and US spellings, for example – but they are official licensed versions, nicely implemented, and a lot of nostalgic fun, which is the idea after all.

imageimage

Trivial Pursuit supports in-game purchases for extra questions, so that could work out more expensive eventually, but nobody could complain about the value.

It is not quite the full board game experience, with wine spilt on the pieces, junior tipping over the board in disgust, and game abandoned early because it is time to visit grandma, but the changes are mostly for the better.

One thought: this is another example of how well a tablet substitutes for physical things. A book, a board game, a photo album: the iPad is a better replacement than a PC or laptop, easily passed round, long battery life, no flapping screen, and a more natural user interface.

I am not sure what are the economics of selling games at 69p, but no doubt EA has drawn the graphs. Currently EA 69p games occupy four of the “Top Paid iPad Apps” category slots in the UK store.

Of course I am interested in the big picture. Looking at user reviews of Android equivalents like Monopoly I get the impression that there are more bugs, partly because EA has a dedicated iPad verson for these games whereas the Android versions are universal across multiple screen sizes, and partly because there are more OS versions and hardware differences to accommodate.

What about other tablets or new entrants to the market like Windows 8 in 2012? Prising users away from their Apple devices will not be easy, though I still think Microsoft has chances if it plays to its strengths in business applications.
