I'm pretty much set on a 14" iBook but was thinking of downgrading to the combo drive. I have a combo drive at the moment and so far it's fit all my uses. i was just wondering what others experiences have been with the superdrive.... i know i won't be making my own movies or anything, do others think it's really worth it for just backing up and data storage or am i overlooking some other possible uses for it?.... what do you guys think?
