Rikki, if you can do most things in your desktop/regular computer then you are set. You would do all your editing there and then transfer the edited files via RW CDROM to you laptop. What's wrong with that. You can keep using your laptop to make music and your other computer for editing.

In fact, I do no editing on my dedicated music computer. All the editing (with some blue screens) on my general purpose computer. It keeps the music computer prestine.
