It's a good reader for individual docs and articles. The gesture recognition isn't perfect, but it's not bad. The software is getting better regularly. I tried installing an ereader (koreader? I forget the name) but it needed gestures that were tricky to pull off (for a task switcher).

Is most powerful feature is it's presence. It's just relaxing to look at instead of a screen.

If you're thinking of one, get it for what it's advertised for. If you want an epaper general purpose tablet, get a boox. I went with remarkable because (a) I liked the use case, I've had Android tablets in the past and they suck; and (b) it's open enough that it'll stay usable even if the company stopped caring.
