Really? I've been pretty unhappy with it on mine. The large, permanent top bar, the enormous window chrome, combined with the miserable vertical screen real estate on my netbook are all... aggravating. The performance on Atom's GPU is also erratic and often multi-second laggy (though it's much better than 3.0 was).
I wound up switching to KDE, which has... strange characteristics, but window management is butter smooth, like you might hope for in 2012. About as smooth as it was before everyone switched to compositing.
