I need some advice on choosing between the MacBook Air (2.13GHz) and the MacBook Pro (13.3", 2.53GHz). I love the MacBook Air's weight and size, but will it: 1) Watch 720p avi files without lagging? 2) Overheat and eventually crash? (The reason why I'm switching to Apple) 3) Able to run Flash applications smoothly? The laptop will be both my home and travel computer. Thanks guys!
