Making a good general UI for E-ink is tough. Amazon would have been the ones to do it, but they put their attention to the Kindle Fire and left the regular Kindles as dedicated e-readers. Probably this was a good thing. Even so, I've noticed that tablet swipe gestures have made their way into the Kindle UI which just doesn't work with the slow refresh time of E-ink.
