> Despite Dasung's promises of "unbelievable refresh speed on Color E Ink" the video makes it appear as if the display's refresh rate might fall somewhere below 60Hz.

Wow, I guess I've been out of the loop for a while. I had no idea e-ink technology had progressed even to 30Hz. I thought it was still very slow, too slow to even try to display any sort of animation, limiting it too e-readers like Kindles. I just watched a video comparing it with the Color Kaleido 3, and yeah, it does appear fast enough.
