The Moto 360 has been released now, and the numbers I've seen say it's 11.5 mm thick, so compared to some of the watches that people on here have measured, not too bad.
The articles I've seen so far have been generally positive, although they often caveat it with statements about it being early days for smart watches and Google Wear.
One of the guys who produces Click for the Beeb posted these two links:

Several people have said that they are lucky to get much over 12 hours battery life out of it, but I wonder how much that's down to the inevitable fiddling, experimentation, and demonstrating that will happen? It may well be that early, pre-release review models, have sub-optimal battery lifes. With the device now out there, live on the streets, I guess time will tell if the hardware or software has improved upon this. 12 hours would be a mite on the useless side, 24 hours has often been quoted as the minimum practical battery life for a watch.
It's tempting, but I think I can forego that much expenditure, since I rarely wear a watch. I may wait and see how the technology, both on the hardware, the Operating System, and the applications, improves.
