So this is really annoying me. I just picked up an air, and the gestures are different than a magic trackpad. I don't mind relearning the gestures, but is there any way for me to have one centralized gesture system? My iMac is still on snow leopard, so I'm not sure if the gestures have changed in OSX Lion, but its really annoying switching back and forth and having to wonder why what i just did not having any effect...
