E-ink isn't that different from LCD tech; if we could make e-ink for $0.50 per screen then we could probably make LCD screens for about the same. The core problem hasn't changed, though: LCD covers more use-cases than e-ink does; it even has better battery life than e-ink in some scenarios! (E-ink screen refreshes take a lot of energy more energy than LCDs, although they only refresh once per interaction instead of 60 times a second) E-ink sounds cool (and is cool), but it's not practical. It's the zeppelin of electronic displays.
