I just can't understand the logic. I understand that there is a viable market out there for the MBA, the question is, how many of those people believe that the MBA is worth it's current price? Look at the iPhone. I feel really bad for all those early adopters who were shafted by the price-drop. What happens after the initial rush is over and Apple realizes they can't sell these things and then drops the price on the MBA?
The OP is a college student. With the HE discount, the MBA is $100 cheaper than the MBP. As others have noted, you're talking about a 2lb difference between the MBA and MB, and a 2.4lb difference between the MBA and MBP. The average student will be carrying around 20-30lbs of books/supplies at any given time, so what does 2lbs matter?
I'm a "non-traditional" returning student in a week, and honestly, the $700 difference between the MB and MBA isn't a major issue for me, but I just can't rationalize spending that $700 in order to purchase an inferior machine, just because it weighs a few pounds lighter.
Based on the OP's comments, it sounds to me like he wants it for the "coolness" factor. I freely admit that I'm a little out of the loop as to what is "hip" these days, but pissing away $700 just for the sake of it doesn't ever seem as though it should be "in".
Just my .02 GHz...
