Products using E Ink's high-resolution display technology were first launched in April 2004 by SONY Corporation in its LIBRIé electronic book device, available in Japan. In addition to SONY, Seiko, Citizen and Microsoft have used E Ink's EPD technology in innovative applications.

Unless e-Paper is getting to be bendable or better foldable it is not really a killer-app. Fujitsu has shown in July a flexible color e-paper.
