I'm in the market to buy a new laptop. I own a Dell desktop now and I'm thinking of getting a Mac laptop. I'm a student (at a university) and I'm looking for advice. I figure the advice I get will be a little biased here but I need info. Also, I want to get some sense of how difficult it will be to switch to using a Mac. I would appreciate any help I can get. I will be using the computer for word processing of course. I'll be using it to do presentations. It'll be that sort of basic computer work that I'll do.
