There is an easy way to get a good discount on any Apple product. Unfortunately most don't know it. Anyways, if you know a college student then have them purchase it for you. With proof they are a student (usually a college ID) Apple will offer a decent discount. That could help pay for it.

And just going to say. Unless you are doing some graphics/processor intense stuff like video editing or massive photo render. Or maybe gaming (sucks on a mac) or running Wine then you don't REALLY need the new macbook. I mean if you want it thats your thing. Just saying the money could be better spent elsewhere.

Oh, and a bit off topic, but if you want to learn about how to hack your mac I can try and teach you some stuff. It only takes about... 30ish seconds to change a password. xD My school uses macs too. Fun stuff.
