hi, so i have no idea if i should get the 13" or 15" macbook pro.. Right now im in high school, but next year i will be going to university. I don't know what i will do in uni but it will most likely be just a general year and take some intro courses in the social/social-sciences. Anyways, Im not sure if i should get the 13" because its easier to carry around (i dont know how often i will be taking it to class though), and its lighter, however the screen size is really small.. OR, the 15" because i honestly love the bigger screen, im on the 13" right now and the screen seems really small and cramped. But i am used to the 17" (old macbook pro), so I might just have to get used to the 13" still. I will be mostly using it for, writing essays, power points, social networking, and I occasionally edit some videos on imovie... So 13" or 15"?
