Queen's has stated that the device is probably about five years away from being available to the mass market, but this is surely a game-changing technology that many companies will love to get a hold of. RIM, Apple, Microsoft, and others will undoubtedly be paying close attention to how this develops.
The prototype cost $7,000 for Queen's to make, but within a few years the school should have that number way down. The key to the future prosperity of this invention is that the price needs to come down low enough so that consumers and businesses will conceivably own multiple e-paper sheets of many sizes. They could utilize them to cover desks, office walls, and board room tables. To be sure, the possibilities in the institutional and corporate environments for this type of technology are immense.
Eventually, the devices will even be able to be folded into your pocket so that you can carry around a huge screen for presentations etc.
