No, the press release is pretty slim on details (volume, price, tech). Presumably the cost/price is OK if they've begun mass production, though -- they'll be competing directly with conventional (glass) e-ink stuff to begin with, so the price will need to be comparable.
Yeah, this is just going to be used in normal ebook readers at first, until it proves its worth. We're waiting a year or two before we have rolled up displays we can stick in our pockets.
Im curious as to what you think the exciting applications are. The article mentions an ebook reader - which is one potential, although I'm not sure it will be something everyone will be clamouring for. I'm (personally) hard pressed to think of other major applications though...
But component prices are often public, and help people predict the cost of devices using the components before they are announced - so still very relevant to consumers.
