Hi, I'm (sort of) happy with my 13" Macbook Air (mid-2011) but sometimes I feel the screen could be a tad bigger and the machine itself could run a bit cooler. Normal things like syncing my iPhone/iPad or charging the Macbook with a Flash Video stream on, the thing gets really hot and the fan starts to blast like crazy. Which of the new Macbooks that were just announced would be the one to go for if I want a cooler running machine and a bit more desktop space? Does the 2012 MBA run cooler than the 2011 MBA? Basically: I want a cooler running laptop. I don't want it to be "much" heavier or larger than the 13" MBA. Bigger screen would be nice but not a must. I guess I have to wait for a 15" MBA? Thanks!
