I'm buying one of these MacBooks, but I also know what I'm probably getting into. I had the 1st gen MBA which was hotter than my stove. Could easily burn my lap when it got hot. Underclocking with Coolbook was the only solution (sadly doesn't work on new Apple hardware) And now the new "Air" is fanless, I would Not play Mass Effect 3 on it. I expect a slick and light computer, but also a hot computer.
