Well and there are large, high resolution full color transflective displays out there! It's really frustrating that these aren't available. My mental health would improve substantially if it were easier to work outside.
Smaller designers who want access to the technology can't get it from a western company, because none are stupid enough to attempt to design a competitor while E Ink the company is still around to sue them.
Fairly recently we've started to see Chinese electrophoretic displays crop up, and I can actually get a devkit or buy them by the low thousand, because E Ink isn't going to be able to sue them in China. But you still don't see them designed into very many products sold in the west, because it would be easy for E Ink to stop the end product from being sold.
