So I'm looking at the macbook air 11" model but i'm somewhat concerned. I was originally going to get the 13" with 4gb ram, but that will cost me quite a bit more than the 11" base. I'm going to be using this as a school computer, and for university. I won't be doing much of anything on it, just surfing the web, youtube, skype facebook ect... my only computer right now is a 10" acer netbook which sucks. I will be getting an iMac a few months from now. So any computer will be a significant upgrade, but the tiny resolution on my netbook makes me wonder how well the 11" mba's resolution looks. I wanted the 13 because of the 1440x900 res, but i'm willing to downgrade if the 13 is an overkill for doing the stuff I want. Also would the 4gb ram upgrade be worth it? I like having ram but do I really need it? I feel like the 2gb will be fine, but I get paranoid about stuff lol.
