Just purchased a DELL XPS 13"and I love it so far.

Pricey but very powerful and light. Remember to get at least 2 GB of RAM if you are running Vista OS (current Microsoft OS) cause the OS will eat anywhere from 0.8-1MB of RAM just to run it. Also check with ur school cuz I know that mine supplies us w/ one. If they do, u might b better off w/ an external harddrive or flashdrive and carry the info to your home comp. instead of carrying the whole comp each day to and from school. Good luck on your decision

and hope this helps.
