One of the first things I did after installing Lion was changing switching spaces/fullscreen apps to a 4-finger swipe and navigating back and forward to a 3-finger swipe. I think I mainly did it because at the time Chrome wasn't "Lion-aware" yet. Like a lot of Apple's UX decisions this is one of the many boneheaded things they like to piss their users off with on a regulary basis.
