3D
I think they are talking about effects like "genie" from OS X and things like Compiz/Beryl. I have seen some movies now that have had Vista in the background, and the effects were there. I have seen Microsoft engineers create these effects, but never introduce them, and I don't know why. I have said it before, if Microsoft wants to give something to the "Ultimate" users, give them these effects as an addon/download. That would be cool, because it would be something I would download.
