Mac it. Since you're a student, you can get a pretty sweet discount. Plus, they just look better.
When I was laptop shopping--it was between the thinnest Sony VAIO that still had internal drives and the Powerbook (12"). The Mac was cheaper, with wireless and Bluetooth combined. With my student discount, I was able to buy a printer and upgrade to a DVD burner and still pay less than regular ticket price.
