This looks like it's just a regular LCD screen though, so it gives off light? The description wasn't very clear on this but the technical specs say AHVA LCD.
I recently built my own e-ink picture frame because I wanted it to feel like a regular picture frame (and it has fooled people already), because it is basically just a printed photo in a nice normal frame. And it looks amazing in direct sunlight, and obviously in the dark you see it less but that's the same with any normal picture frame.
If color e-ink was ready for this use case it would be pretty cool, but I think we're still a while away from that. It might also be too expensive.
