In theory they should be amazing. Full color, looks like paper, basically an interactive magazine!

In practice the color isn't great, the screens are slow to refresh in an annoying way, and the resolution is a noticeably worse than an iPad. I also find that apps not explicitly made for e-ink are generally garbage when used on an e-ink device.

So far I have personally been incredibly disappointed with e-ink devices outside of e-readers. I want them to be good but the experience is just so much worse than an iPad.
