Now, I know this'll sound like the usual nutcase's rant, but they are slow, and I hate that!
I hate having spent almost 1800€ on my mbpro (it's the basic santa rosa model), and see that spaces and expose stutter heavily, especially when a friend at work was using a ultracheap Celeron with intel X3100 under Linux (offering the same effects), lightyears faster and smoother...
I love OSX, but I hate spaces being so slow (expose varies... first time sucks, then tends to become smoother).
Sorry, had to vent, got too angry yesterday! :-)

P.S.
I'm curious... what's the mileage on MacBooks?
If it's similar, then are we really using a non hardware accelerated gui?
