Notice at the vid start they showed GUI networking because they're aiming Win8 at touch-screen people who chat and look at pics and would soon get bored. Other useful details were later in the vid. And Windows Live... it came with GTAIV XD Maybe there will be problems again with compatibility since they're only pushing Windows stuff: Windows Live - Explorer; Bing; Outlook...Although besides the Windows apps it's the way things are going - even UDK has iphone; xbox code and they'll probably introduce a twitter connection But there's Google who are working on an operating system and want to take Windows' market... could be interesting.
I think what Google was making was just a minimal/simplistic Linux distro, targeting netbook users and such. Not really a competitor.
EDIT: I wish Windows had a transparent terminal emulator (cmd) like most Linux users are using. That would be even prettier.
