I've had MacBook Pro's for about 3 years and I've been running a MacBook Air for about 9 months. I love my Air, it's easily a very solid machine. But the small screen size can be a little constraining, and the machine does noticeably lack power. Not having a dedicated graphics card also limits you from trying out things like WebGL. And anytime you hit a Flash-based website, your MBA will sound like a jet engine. I think if you're very mobile (i.e. travel a lot) go with the Air. If you're at home most of the time, get an iMac and an 11" air for the few times that you are mobile. If you need the best of both worlds, go with a MacBook Pro. My next machine will be a 15" next gen MacBook Pro. Those should incorporate design elements from the Air in a more powerful package.
