I currently have the 2011 MBA (13 base model) and Starcraft runs okay on it, but the area where the processor/graphics card is, especially right above the keyboard, gets super hot (and by that I mean if I kept my finger on it I'd probably get burned). Also, the fans run like mad and the thing sounds like its taking off into outer space. This happens even on the lowest graphics settings in native resolution (1440x900). So while it plays fine, it's a little troubling I guess. I worry the thing will overheat, especially if I ever end up playing it somewhere hot without AC. I am wondering if this is still the case in the 2012 model or if the fact that the Hd 4000 is a better card + better processor + more RAM make a real difference here. Also, is the 2.0 Ghz model worth it? As in, would it be able to handle a game better thus not force the fans to kick into highest of gears all the time? I am debating going with the extra space (256GB) so if I go with that I might as well go with the processor but if it's not worth it maybe I'll stick with the 128GB model and just try to cut some crap out and save the $400. I am actually going through a phase where I'm getting rid of all my stationary things like my iMac and going all mobile (getting ready to travel heavily starting the fall into early next year). The only game I play is SC 2, otherwise my needs are pretty mild (just typical office stuff). The MBA will be my only machine for at least the next 8 or so months.
