I'm thinking about switching over to the dark side and becoming a Mac. I need to decide what I want by the end of May. At first, I was debating between a MacBook and PC. Now I've thrown in the possibility of a MacBook Pro. What are your guys' opinions on all 3 of my options? Specifically I'd like to know the differences between the MacBook Pro 13" and 15". And also the MacBook and MacBook Pro. I'll mostly be using the notebook to work on school stuff, reading power point lecture notes, writing essays, surfing the web, storing a crap load of pictures etc. Nothing to big. Suggestions?
