I'm considering getting a maxed out 13" air for portability. The only thing is I want to make sure I'm not losing performance. I tend to use heavy apps like aperture, final cut pro, and maya. in early 2010 this macbook pro 15" with GT 330M graphics and 8GB ram was the best laptop you could get for that. Today, most people would tell me do not get the Air for these apps - but really, wouldnt I be able to expect similar performance with a boatload more portability? With the Air able to get 8gb ram now, I'm very tempted to jump on it. what do you think, should I switch to an Air?
