I use my powerbook for pretty much everything here at school. I decided that I didn't need to bring my desktop PC with me this year, and I haven't had any need for it so my choice has seemed pretty good. I use it mostly for taking notes in class, keeping me occupied while running reactions in the lab, playing world of warcraft, browsing the net, talking online, lite photo editing, web design (with the macromedia MX04 suite), listening to music, watching some DVDs, etc... normal college student stuff. I also store a library of all my work on here, lots of slides from classes to study, etc...
