That's not an e-ink device though, right?

I was trying to find an e-ink tablet, amazon kept recommending me the magic notepad from xppen. It looked good, but I wasn't sure what that cryptic "x-paper display" was. The wording is just vague enough to make you think it's an e-paper display, without committing to that detail.

It took going through comments to find out that it's not an e-ink display.

The Daylight computer seem like that too. So what do you think of the display? Is it just another LED screen, or does it approach e-ink in any way?
