It's nice as long as your document fits on a single page. Otherwise you need several of them, and it won't allow you to scribble on it or highlight stuff.

IMO this is still less functional than an ordinary sheet of paper, this just solve the energy issue, but not much else.

I'd still probably go with a powered one just to get the benefit of swapping pages and taking notes on it.

On the other hand, if the can manage to make something that can power them over a longer distance than typical NFC, I could see those used for in-office digital signage (meeting room status and schedule, employee schedule, etc) which doesn't require a battery swap, PoE or some other kind of way to power it.
