Get something light, so you can take it to class easily. Also, don't get one with a CD/DVD/BluRay drive, it's just added weight. If you can use the school's computers for the first term, it might be better to wait and get your laptop after Windows 8 is released. There will probably be a bunch of new hardware at that time and current laptops will be a lot cheaper.
Personally I don't spend more than $600 on a laptop anymore and just upgrade every 2-3 years.
