E-ink usage has been underwhelming/disappointing. When the technology was first announced I thought it would take the world by storm, but all we wound up with was eBook Readers and little else.
I really hope that color is the missing piece of the pie, and we'll wind up with color e-ink photo frames, LCDs in adverts displaced by color e-ink, and even secondary screens which are e-ink based.
It is such a cool technology, almost zero energy use between updates, that has been ignored and under-used. It legitimately makes me sad.
I guess nobody wanted to be that "dated" manufacturer who used a black & white screen on something in 2016, no matter what the benefits.
There are two things holding E-Ink back: 1) Battery life alone is not worth the tradeoff for the consumer market. 2) The flexibility of the form factor could've taken E-Ink places that others couldn't go, but: a. The company makes it very difficult for startups to work with them on non-stock sizes/shapes. b. The manufacturing process hasn't improved enough to bring the promised cost within reach.
All the R&D money in the display industry is being invested elsewhere, and people will get affordable, flexible, and high-contrast OLED screens sooner than E-Ink can check off two of those boxes.
