Now I realize that the Macbook Air seems to be the forgotten stepchild of the line, just as the AppleTv and mac mini were at one point, but as I've walked around business school at Duke, I have noticed an increasing amount of Macbook Air users. Many administrators and teachers (though Fuqua may encourage it) around the school possess a Macbook Air and many of the MBA students. It seems that Apple did quite a good job of hitting upon this niche market, it's just a shame it did not catch on to a larger base of users. I'm using a Rev. A, 1.8, 80 HDD going on 2 and a half years now and it still works fantastic. There are some things I wish I had gotten in the subsequent Revs, but seeing fellow airs around campus brings a smile to my face and is a pleasant reminder that I'm not the ONLY one out there, who has enjoyed this laptop!
