I'm looking to buy a laptop to bring with me to classes for taking notes, researching, and writing essays. I do a bit of photography and coding on the side, but nothing heavy. ...So I've got two questions: 1) is the Air a good choice for me? Can any other college students speak to this? 2) Should I go with the 11" or 13"? Considering the amount of reading and writing I plan to do on the machine, I'm leaning towards the 13" -- but then again, the Air is only attractive because of its small size, so isn't buying the 13" counterintuitive? The 11" is just so sexy! I feel like I'd be able to pull it out anywhere at any time. Maybe the 13" is just as small and portable though. I'd like to hear some opinions on this in particular. Thanks!
