Windows 7 will be on sale pre-installed from 23rd October 2009, according to plausible leaks. So much for “when it’s ready.” You heard it from me first though: on 29th October 2008 I posted that Windows 7 may be less than a year away.
The OEM vendors need at least a couple of months to prepare and distribute their machines with the release build. Vista was done on November 8th 2006, even though it was not “launched” until January. RTM July for Windows 7?
