<p>I'm on campus with a mac powerbook g4, and it has served my needs very, very well. Macs are completely compatible with everything on campus (and offer student deals for Williams students), so don't be afraid to look in that direction if you're not sure you want a Dell. Jesup will service any computer (laptop or otherwise) with a problem that they are equipped to deal with. Mac and Dell both have very good customer support for things that Jesup can't fix. </p>
<p>You should definitely get a wireless card. Right now there is wireless internet available in the science library and in a few other places on campus, and it will be in more places in the future.</p>
