I don’t need a new Mac laptop. Ok, I admit, that’s never stopped me before. But really, the MacBook Air, stunning though it may be, is not for me. I do lust after the multitouch trackpad. I’ve been reaching to pinch my screen while viewing maps since a week after getting my iPhone. I’m ready for it. But there are too many limitations for it to be my primary computer, and I don’t want to go back to messing with keeping multiple computers in sync.
