I picked up my Macbook Air, yesterday, and fell in love with it immediately - everything went over fine, and it started working out perfectly. Today I went to my several classes, messed around afterwards and during lunch, and was on it at the library this evening. *PROBLEM* I opened a .ppt file in Keynote and in MS Powerpoint, hit PRINT and then it went berserk. 6200 rpm fan speed, along with up to 80•degree CPU temp, and in my iStat Menu the Core%Usage kept jumping 100% from one core to the other. -> The process that was supposedly eating everything was "cgpdftoraster" as high as 100.0% W.T.F. ?!?!?! In panic, I shut my computer down through the menus like normal, let it sit for like 5-10 seconds, and pressed power to boot up. Within 5 seconds of sitting there after my desktop came up, the cores activity shot back up to 100% jumping in between the cores with the same "cgpdftoraster" process, fan at 6200 rpms. - as a side note let me say that my 1.6/80gb Air ran for 5 hours, 33 minutes today. Not even kidding. Wireless was on and off intermittently when I was surfing or getting distracted, brightness was 50%, and I was taking notes and running Keynote. - I was terrified when I saw people saying they only got 3.5 hours out (which still isn't bad at all) but I wanted *great* battery life, and after today's experience, I couldn't be happier. Again, I'm not real sure how I got such amazing life when others supposedly aren't - maybe it's the wireless on/off, and that I'm only taking notes/power-points; Regardless, today on the first charge I ran 5 hours and 33 minutes cumulatively today just after turning to 1% left. Other than *this problem insane fan/processor problem that was plaguing my Air, I couldn't be more satisfied with the product.
