Love what you guys are doing with Joan.
I strongly believe there's a place in the market for displays that don't feel like displays. I don't think there's much need for interaction, but passive emitters of relevant, useful, hyper local information that feel like a wall feature or design piece rather than screen could have high success rate.
I built a Smart Mirror for this purpose. It was mostly a mirror, in a nice wooden frame, but it also subtly told me when the next bus running down my road would be and whether or not I needed an umbrella that day.
The only reason it's not back up on the wall yet is because it uses a backlit LCD which is fine during daylight as the half mirrored glass hides this with enough light, but at night it's all lit up. If it were backed by OLED instead (impossible at a 24" size) it would feel much more magical.
There's lots of other ways of taking the same approach - furniture / feature first, display second, that I think could succeed as a popular product.
