I think you misunderstand me. I'm not against 3D and I'm not talking about hardware acceleration.

@allnamesareout and Capt'n Corrupt: The things you describe are just 2D done with hardware acceleration. I'm talking about things like 3D cubes and animating windows (axis rotation or melting to statusbar like in OSX and Compiz). They sure are pretty, but if you are trying to do something fast - they tend to just get in the way. iPhone out of this (didn't see one), but HTC TouchFLO is horrible and the various touch interfaces based on gestures i've seen are pointless and slow (not the effects, but the usage). I'm still using them though, since WM is even worse.
