I have been waiting for several years for color eInk displays to come about. I am fine with a refresh rate of even something like multiple seconds. Thus far the only thing I have found are companies in China that are willing to fix a single image on a color eInk display (no idea what the point is if the image can't be changed, but that is my understanding) before shipping. I haven't went hunting within the past year or so though.. anyone know if there's been any progress on that front?
