I'm waiting to upgrade my Rev A MBA and was about to pull the trigger when the port of Civ 5 was announced. This is close to beign a killer app for me but I never got into Civ 4, partly because I never had a machine that could do it justice. Civ 5 comes out tomorrow, as readers of MacRumors who've clicked on this are no doubt fully aware! I am itching to buy both. Ideally, I would like the maxed-out 11". (Yep, had two Duos back in the day. Yep, had two 12" AlBooks.) I would love to play Civ 5 on it - and I'm, talking about on planes and in hotel rooms, not as a gaming rig. (I am resentful that they took a game which would play on a Duo 230 and made it a graphics CPU fest but that is also a digression.) I know there are compromises; the question I have for those of you buying it tomorrow is does it work, and if it works, is it playable enough to be fun, or is it just wretched? 1.6GHz with a 2.4GHz stated minimum is a big ask I appreciate but I don't require the eye-candy, just the challenge. I can live with an occasional beach ball etc., but not hangs and crashes. If it doesn't work I would buy the maxed-out 13" which looks much closer, at 2.16GHz, particularly when it seems to be benchmarking so well. Early buyers, does that work? If it just doesn't work at all I will likely not bother, buy the 11", and stick to Civ 3, and maybe try the Boot Camp version as the PC minimums seems lower. But I would prefer not to have to put Boot Camp on a 128GB drive, to say nothing of the nastiness of Windows...!
