To be honest, I'm more interested in Paperight as a POD platform for the first-world, not the third. Paper books are never going away, but as online sales continue to encroach on brick-and-mortar bookstores we're going to see fewer and fewer opportunities to get a needed book right away. In fact, this is already a problem; even the major chain bookstores are finding it necessary to devote more and more space to non book items.
But that's no big deal; the platform can fill both needs.
