Any laptop with wifi, a cd burner, usb ports, the latest word processing software, very good battery life, and 5 lbs or under with looooots of memory will be fine for college.
Remember though, if you get a laptop with more then 3 gigs of memory you better have a 64bit os and cpu or you are wasting your money. 4 gigs seems to be about the sweet spot right now for memory. Anything less is not enough and anything more is overkill.
Macbook should be fine, but remember it'll be way more compatible if you run something like microsoft office and not apple works.
Oh, and if you want to game .. that's fine, but try to do that on a desktop. Leave the laptop for school work i.e. typing up papers, creating power point presentations, doing research, etc.
