I also own a Dell XPS 1330. I've always owned Dell computers and I used to swear I would only buy Dells, but this one has changed my opinion a bit.
This is the most I have ever spent on a computer. I had a lot of things upgraded when I bought it and I was attracted to the fact that it is small and light yet powerful. However, I've had problems with it since day 1. I've already had to replace the hard drive (thank goodness I faithfully back up onto an external hard drive) and I get the blue screen of death at least once a week. Have no idea why. I would call Dell, but I was on the phone with the tech people for HOURS over the hard drive and frankly I just don't have the time to waste while they run every test under the sun.
If I had it to do over again, I would really shop around and find a deal at one of the big box stores on something equally small, but maybe a litte cheaper and less powerful. I think Dell is getting too big and their customer service (which used to be pretty good) now sucks. You don't need a monster computer for law school. Unless you're a gamer or something, just get a really light computer that will do the basics and save your money. That's all you need.
