I'd really like to have a decent (let's say >13") display to hang on a wall in my room and display weather, my todo list, etc. It doesn't necessarily have to be E-ink proper, but I like the idea of having something that doesn't emit its own light. More like an electronic whiteboard.

Alternatives include something like the Vestaboard, which is not cheap, and probably fairly noisy.

Are there products I'm missing here?
