wPod said:go for the MBP. my 15" PB with a 20" external monitor are the best things for college. you have a good 20" monitor for doing work when your at your desk, and a powerful machine for going to class with. thats just my experience in college, but its still a great set up, though some people dont want the external monitor.
I think getting a set of external everything is great for a laptop of any type if it is you main computer.
External monitor, Mouse, Keyboard, speakers, Hard drive if space is needed. And maybe even an extrnal web cam if you plan on using it a lot. Oh yes and a USB 2.0 hub.
That way you have all the advatages of a desktop and the portiblility of a laptop.
Also there is a good thread on other items you are going to want to bring to college down in the commenity forums that I started a while ago. I would recomend looking at it.
