They would need to get the thickness of the superdrive down, as well as it's power draw. Either that, or come up with even better battery technology to allow it into a laptop/TiBook. Another thing that is keeping me clear of the superdrive is the speeds... when they get the cd burning speeds up to what you see cd-rw drives at now, then it could be a more viable item. Right now, it is more of a niche item.
