Looks promising ... 'cept that what it is remains unclear. Seems sort of a robust wireless headset extending the phone which remains in your pocket...but it's a lot smarter than just a headset...but it's...uh...a lot of cost/effort to save just pulling out the phone. Getting there, got a ways to go. Put the actual cellular radio in there and you've got something.
If only they would give it a bit of personality (a proper name, for starters) - could be a hit.
