What you say could be correct for a lot of technologies, but not this one. E Ink tech do not have much traction because of "E Ink" the company and their patents. Basically it's highly proprietary and they dont want to give away control over know-how and production. Until major patents expire no one will it touch with a ten-foot pole.
