captfitz: it costs $100 to ship my desktop and monitor to college. i can put a laptop in my travel bag for free.
Thats a lot of money to ship stuff but I'd lay odds that the vast majority of it is the case. If you're paying 700 bucks for this thing, why not pull your existing PC to bits, take the major components with you and get a new cheap boring beige box (or B3) case locally to reassemble it? It'd cost a lot less and you could probably get a new video card or something as well (which would be one less thing to carry). An Antec 300 case would set you back about 60 bucks, add 40 for shipping the monitor and that leaves you 600 bucks to buy a shithot video card with.
A laptop would be easier and would do the job but the important parts would never be able to be upgraded so it'll be the same PC forever (yes technically some can be upgraded but its more work than its worth) so you're buying tech thats already a bit too old to run modern games and will only get worse. If you don't mind that and/or aren't too confident on pulling your main PC to bits, a lappy might be a good plan.
One thing I'd suggest is loading up the Dell site and having a look through their stuff, they often have good sales on and if you can find the link to the dell outlet, you can get a fuck of a good bargain. They seem to hide the link amongst boring crap, on the australian version you have to go into the details for one of the lappys from the main page and the link is then in the left sidebar. The outlet sells cancelled orders, stuff thats been made but was never shipped or shipped to the wrong place and returned, you can't modify the systems at all but you can sometimes find a few hundred bucks off on a good bit of kit
