I am buying a Macbook Pro for school and I don't know which size I should buy. I originally wanted the 13 inch, but now I'm wondering if the screen will be too small (which may be annoying when I have to spend a few hours working on school assignments). I started to think that a 15 inch would solve my problem, but I'm worried about portability - especially since I'm very petite! What do you recommend? (p.s. budget is not an issue)
