I've said a bunch of times that I really really wish that Pebble had gotten a chance to finish the Pebble Core:

This reminds me of that in a good way – a small Linux device that doesn't have to maintain a screen all the time (power) or focus on real-time but has physical buttons, connectivity, a microphone and a sealed case so it can be thrown in your pocket would be... an absolute dream.

Counter to some others here, I would buy this at whatever cost if it lived up to that intent!
