Been lookin around today at the Air i5 & i7s running games - quite impressive. How's the heat though? I game on a Macbook Pro 13inch 2010 at the moment (my 15inch MBP is nearly dead) and the only time I have problems is when running 2 instances of a game (like multi-boxing on an MMO for example). The problem isn't the processor or graphics card.. they run it decent enough to be playable.. but the heat. As soon as it gets hot.. everything throttles down and FPS dies. I can solve this by homemade cooling (icepacks under it) it's a hassle. Luckily I don't multibox often, or even play often right now, but I will again in the future and the future looks to be a Macbook Air 15 or 17 inch if rumors are to be believed. I like the sound of that. More than fast enough to work on and lighter too. But I'm worried about the heat. If my MBP 13 inch and 15inch got so hot that they started to slow down, then the Air surely must be worse. Anyway, sorry for the wall of text - but figured the Air owners that actually run games would be the best guys to ask. I've never used an i5 or i7 machine.. just Core 2 Duos..
