I am another one of the "ibook update" people, impatiently waiting for an update/refresh so I can make the switch to Mac from my much-hated Dell. I am a grad student in History and have recently started using a digital camera for a lot of my archival research. This means I have a rapidly growing photo collection that is mostly high quality images that I want to back up in several ways. I would prefer to keep them in high quality images, as they are images of faded handwritten originals. Can these be burned to DVD instead of CD? Should they be? I wasn't going to get the superdrive option on my ibook, but now that these files are getting so big, I was wondering if I might need it. Also, what is the price difference if I got a combo drive and an external DVD burner for home? I have never even had a DVD drive on my computer before, so I am not sure what I can use it for.
