I must say, I love this feature on the Mac OSX. it uses OpenGL on your vid card to handle the effects and windows on your desktop so it can save precious cpu clocks to do other things. My question is why the hell hasn't Microsoft copied this awesome feature yet? even if the majority of regular avg users don't have good enough video cards it would be nice to see it supported via a feature you can turn on and off. Perhaps it will be available in Longhorn? or something like it at least.
