Charbax has posted a video of a recent booth tour where E-ink shows off its latest concepts. Watch carefully and you'll see flexible smartwatch displays, a color 13.3" E-ink screen, and an eBadge design that is powered by NFC.
There's even a concept design for a dual-screen smartphone like the Yotaphone.
For the most part, what we see in the video are less products than they are potential products. I wouldn't bet on seeing these devices hit the shelf any time soon, but this video does still give us a good idea on what E-ink could do if someone had the money.
