Hi, I, like many of you, were really hoping for a 13" retina pro. Now that one wasn't released, I think I may need to go ahead and purchase something because I am taking classes and only have a desktop. That works fine when I am at home, but I have some work trips this fall and will need to stay up with my classes on the road. So... I was thinking of buying the 13" air now and selling it later if a 13" retina pro is released. I know I will obviously lose money, but I guess I would consider that the price to have a laptop the next few months (or longer). My question is, if something is released this fall, what are your guesstimates on how much someone could get reselling a base 13" air? I am just wondering how much I stand to lose by going this direction. Any insight? I know it is just guessing. Thanks!
