It is kind of cool, but even if the price comes down, the utility is limited. It would be great for companies and schools who have to distribute printed memos or meeting agendas (why would they still do that?), but not much use to home users who print out bills, emails, and what-not that they intend to keep for years. Some universities are going to all electronic-based texts, and I think that's the real trend. If you can get a document in easily portable format, wirelessly, anywhere in the world, what's the use of re-usable paper that has to go through a machine to be re-used? The PrePeat looks like a fantastic technology, but it might just be another Betamax.
