Depending on your major and budget, I generally support laptops. Get a good quality one if at all possible, as it's nice to be able to do assignments wherever you want. Desktops are only worth it if you're on a super-tight budget or if you need super power for work. (Like graphic design, architecture, etc.)
Unless I have some sort of epiphany, I'ma be majoring in music...I'll have to think it over to see whether or not I'll need high specs or not. Thanks. ^_^
