I know that e-ink type displays can be made flexible, but again it's that durability I'm worried about.
Like you said, many companies are working on that very problem right now, but I dunno if we're there yet. Considering how much *any* e-ink device costs right now it feels like we're quite a ways off from having anything commonly available like what they are talking about in that video.
I'm not saying it's not cool or that it'll never happen, just seems a little premature.
