I don't actually *use* Windows, but from everything I've read, the only features that people actually wanted were dropped. All that remains is annoyances and a heft price tag. UAC appears to be broke in a serious fashion and not being "fixed". The DRM will be terrible. The one care stuff will probably suck, and it's likely that it will incite all sorts of anti-trust stuff from anti-virus vendors. The networking (they rewrote their entire tcp/ip stack) has been said that it will somehow break the internet (I've got nothing of substance here). Basically they took BSD code that had been working fine for years and rewrote it windows style... so it will probably be buggy. WGA and that stuff will be a requirement, so bill gates spyware = bad, and no you can't turn it off.
