I'm going to be in ap computer science next year and then independent study at college level with computer science. I use my mac for typing essays, music, web surfing, and doing comp sci assignments with programs like Blue jay. Sometimes I do graphics design or 3-d modeling, but i'm not a gamer on my mac Which 2010 updated macbook pro should I buy? The 13 inch with core 2 duo and better graphics vs 15 inch with core i5? I'm gonna bring my computer to school everyday and the 15 inch model makes me worried about portability tho Ideas??
