I am starting to regret that i didn't get the superdrive with my new powerbook. I have a lot of big files on my computer and the only way to get the off is to put them on dvd's. Is it possible to hook up an external dvd burner. I heard this wasn't possible from a few posts i've read but i don't know for sure. If anyone could recommend one that doesn't cost too much. Just need something that will do it's job and not die on me for a few years. Thanks.
