What does Vista do that XP doesn't which would constitue a rollout of 000's desktop? (other than the fact Microsoft stopped supporting XP...) > nothing
A lack of support is complete reason enough. As far as I can tell, 'not supporting win XP' means no more updates, etc (correct me if i'm wrong): if that's the case and some hacker or other finds another exploit in XP beyond April 2009, anyone who has an XP machine will be a sitting duck if that exploit gets exploited.
Additionally, as I and others have mentioned in this thread, Windows Server 2008 is said to provide a lot of vista-specific functionality.
Big companies dont move until they HAVE to, and they wont have to if Windows 7 comes along in 2009 (and it's stable),
But if MS can't get Vista stable enough (as apparently its not), what are the chances of Windows 7 being stable enough, at its release? If it gets released in 2009, as it's said to, it won't be until 2011/2012 before companies actually start using it. And in that time you expect them to continue using XP?
Bill Gates has also said this of Windows 7 being more 'user-centric':
Bill Gates said:That means that right now when you move from one PC to another, you've got to install apps on each one, do upgrades on each one. Moving information between them is very painful. We can use Live Services to know what you're interested in. So even if you drop by a [public] kiosk or somebody else's PC, we can bring down your home page, your files, your fonts, your favorites and those things. So that's kind of the user-centric thing that Live Services can enable.

That to me sounds like one massive experiment. For a company to subscribe to that at its launch would be even crazier than justifying not moving to Vista right now.
