I'm curious about the refresh rate. From the video, it appears to be fast for an e-ink display. However, it still seems to be slower than what I'd be comfortable watching a video with. The other thing I'm curious about is the manufacturer. They seem to have a black-and-white version already available. Has anyone ever tried it?
I cannot understand the fascination behind seeing e-ink displays play video. The tech is a "display once, use forever" kind of display. Otoh, video needs bright vivid screens, gaming level quality. Quite the opposite of what a "display once use forever" tech would be suitable for.

And different video effects are optimal for different environments (e.g. lightning).
