I think what this needs is to integrate Delorme InReach capability, or something similar.

Current e-paper tech is a double edged sword. Good in sunlight, low power, but the slow refresh will likely make a painful general purpose Android tablet interface.

My guess is they are going to have their own interface to try to hide this somewhat, but it will be interesting to see how well the interface works, and it is unclear if you'll really be able to load your own apps on there which I think detracts from the value quite a bit.
