Ugh.... I always get stuff like this: "Wow what a crappy screen, its not even color" or "Why doesnt it even have a backlight?" or "Its annoying that the screen flashes black sometimes. Screens shouldnt have to do that"
Ive explained the concept of e ink more times than I care to remember
The flashing used to bother me, I don't notice it anymore. But complaining about a the screen being black and white, or complaining about the lack of a backlighting doesn't seem like complaints a reader would make. Don't get me wrong, I know people complain about them, but books are generally black text on white paper, so e-ink isn't any different. And paper books aren't backlit either.
Just a few years ago, e-ink was science fiction. Some people want to predict the end of e-ink, thinking we're all going to go with LCD. E-ink has so many advantages that it is here to stay.
