Android Wear, the OS used for the Moto 360, has a lot of built-in voice support for everything from playing music to getting turn-by-turn directions.
Motorola's lead designer Jim Wicks, said the round design fits more surface area without corners cutting into your wrist. Also, the intent is to make the Moto 360 appeal to as wide a range of people as possible, both women and men.
Just one button (and the touchscreen, of course) and no port for charging, which is apparently done wirelessly.
The Moto 360 as well as the Android Wear watches coming from Samsung and LG are water-resistant.
