Why people are obsessed with e-ink screens?
Every once in a while I see e-ink screen hardware popping up on hacker news. I'm sure there are other kinds of screens that can do a similar effect such as Pixel Qi. But I don't see them that often.
one of the best features is that is doesn't need energy for maintaining the screen. Only updates require power, so its perfect for low power applications.
You are sure? There are almost none, that's the point!
