Interesting... nice website there btw, not what id expect to see on the MS site. Flip 3D sounds cool, i wish that Alt+tab in OSX would sort of flip the windows to the front of the screen as you press so u can see ^_^
I guess Microsoft are getting a bit worried about OSX's success drawing people away from PC's (and so their software). It looks like an evolution of XP though, not a revolution. 🙂
Biggest thing is, protecting the Operating System from 1)users! 2)malware/spyware 3)virus's
They should approach it like Apple, make the user put a password in BEFORE any vital system changes can be made - not admin - hard luck. System Restore is also messy - it could do with axing and them trying something else.
