Google wearables: take two.
Believe it or not, Google has been a leader in the wearables space for some time with Google Glass. Glass gives users fast access to information and an easy way to see and deal with (certain) incoming notifications, but the form factor is physically and socially awkward. Wear seems like an evolution of the quick information access that Glass pioneered, all in a more comfortable, less invasive device.
I've used quite a few gadgets in my time, and I've never seen anything become as instantly useful as Android Wear has. It's not just me, either. At Google I/O, every attendee got an Android Wear watch, and after a single day, it seemed like everyone's behavior had changed. A notification sound would go off, which would normally send everyone within earshot rummaging through bags and pockets, but by the second day of I/O, we all just learned to check our watches. Strapping on a Wear watch for a few days changes your mobile workflow. It's an extremely useful device that I plan on wearing from now on for the simple reason that it makes me more productive.
