I was thinking the MBP because it's user upgradeable, but I would LOVE for it to be the Air. I have a 2011, yes 2011 MBP and I think I'm returning it for the Air. I just think that choosing between the 2 at the same screen size, the Air appeals to me more because it is lighter (much lighter), faster because of SSD, and has a matte screen with higher resolution. The Pro benefits from the Core i5 processor and the backlit keyboard, but I don't do anything that is processor heavy, at all. I do light things like web browsing, Microsoft Word/Excel/Powerpoint, use iPhoto, iTunes and I use Parallels for school but not too often. All in all I'm going to benefit more from the Air, but I'm hoping I can still sell it for around $900-1000 when there is a refresh because I do like having the latest and greatest.
