I am currently going into my senior year of highschool, and after an extreme distaste in my mouth from my Toshiba Satalite (screen has a large green line and it crashes every 2-3 days! Never been dropped and no viruses) I have decided to go mac! I am expecting this to last up to 5 years( final year of highschool + College 4 years) without giving it relief from purchasing a new one. I want whatever I purchase to be functional in society uptill i get out of college and be reliable word processor, web browser (mostly youtube ect. but heavy use), and light photo/video editing. My conflict is between the 13" macbook, 13" MBPs, and the 15" MBPs. I want it to last and still be functional 5 years from now. My Budget is no more than 2000 including tax. What is your suggestion?? Should i go to the 15" entry level or stick with the bottom macbook?
