Before you point out that there is a guide: http://guides.macrumors.com/Which_size_MacBook_Pro_should_I_buy I want to say that I read the guide, and it pretty much told me to get either the 15 inch or 13 inch... which is my question.. I'm majoring in Information Systems, which would require a handful of programming classes, I plan to run parallels on it. But I'm concerned if a 15 inch would be too big to lug around to classes or fit on a desk. Any thoughts? Anyone with experience in this area? I just feel like a 13 is too small and 15 is too big. I imagine i'd take the computer to most classes. I plan on doing a *little* video/photo editing. Maybe some website stuff. Mostly portability and productivity.
