I tried editing on my Toshiba 2.8Ghz laptop and it was far far slower than my dedicted desktop PC. Laptop hard disks usually spin slower than a desktop PC. 60GB is a little small and you'll eat that space up very quick if you do even a moderate amount of editing. If your serious about editing, you should really have a second disk just for your video files. A bigger external firewall hard disk would help though.
