There was a thread on here somewhere a day or two ago about this device and now I can't find it.
I was over at CES and found them--one of the partitioned rooms at the back of the bottom level of the south hall. One sign out front, two people talking in the room, that's it. Obviously it's not a finished product yet.
In looking to see if I wasn't finding it due to a spelling error I stumbled upon this video about it:

Edit: When I tested the link to make sure it didn't get broken the audio worked.
He's saying $50 for the device, $12/year for the service and while he didn't specifically say it's available now he certainly sounded like it was ready.
