60Hz is not mentioned anywhere on the Kickstarter page. That's just shoddy reporting AFAIK.

The article has a video showing smooth scrolling on the screen, which is completely impossible with current e-paper technology, unless there has been a recent revolution that I'm not aware of.

I was going to say, that "video" of the e-ink screen looks a LOT quicker to refresh than anything I've previously seen.

I remember seeing e-ink panel demos where the integrator claimed the usual slow refresh was a side effect of the low power requirements rather than a limitation of the panel. They claimed that a controller designed for fast refresh could show moving video on an e-ink panel. It kind of makes sense because you can address individual pixels in the panel and they can change state faster if you apply higher tensions. The trick is to refresh the whole panel at least 30 times per second.

You can also fool the human brain by rendering motion blur.

15fps already looks kinda cool on eink, even with the ghosting artifacts. Not that I'd recommend watching movies like that, but still. Harry Potter newspaper in reach. :)

This is true on black and white eink displays.

But for color, I'm not so sure.

you are incorrect.
