So I went to the apple store today and did just about as much as I could to get the new 13" i7 air to heat up and I couldn't do it. (Regarding the fan noise, I was in a loud apple store so I couldn't test this). This may be a super simple and lame test, but I opened every app on the dock, I then left them all open while playing 3 separate 1080p videos on youtube and copying the 10 gig itunes library multiple times to the desktop. I did this for about 20 minutes. I checked with my hand along all the regions of the laptop and it never ever got even close to getting "hot". I could have kept my hand on it for hours without feeling any discomfort I also did this with the 11" i5 air and it also never got beyond warm. Sadly this apple store didnt have the 11" i7's on display WHICH I SO BADLY WANTED TO TEST.... I would very much like to hear from any 11" i7 users about how warm the aluminum gets. Please give insight if you have used an 11" ultimate.
