I'm not sure if anyone has any interest in this device. I haven't seen any threads on it. But, I received mine in the mail today. It's really small, which is a good thing. I was surprised to find out the middle circle isn't a button. I guess I just assumed since the larger TT had one, this one would to. I have a 1520 with dev preview on it, and so far no issues with the functionality. One small disappointing thing: you can pin various connected devices to your phone's home screen (MS Band, BT headphones, etc) but not this. The stickpin icon is greyed out. Anyways, a few pictures:
