Greetings all, I'm currently using a 17" HP Pavilion that I purchased back in 2006. I'm very comfortable with Windows and will be purchasing an Ultra-slim PC for when I begin business school this upcoming fall (it will be strictly dedicated to school). That said, I've tired of some of the issues with PC's and am considering a MBP for personal use. I primarily will use this for music, movies, and internet, and am looking for bang for my buck. I don't really play games (and the ones I do play are more "strategy" than action). Right now my dilemma is between the 13" MBP and the 15". I don't think the upgrade from 2.4 GHz to 2.66 GHz is worth the added price at all. I'm pretty sold on the 13", as it is cheap (relatively, plus I get a student discount) and is lightweight for easy travel (plus increased battery). My primary concerns are the resolution of the 13" vs. 15" screen, and just general functionality. I've never had a laptop screen smaller than 15", but don't know that I really need it, given how I will use it. Does anyone care to opine on the 13" vs. 15" debate? Thanks in advance for your help.
