It actually looks interesting. It works with your Iphone, so you could read emails and texts on it and respond on your phone. I expect there to be an android version soon.
Samsung introduced the Gear smart watch line back in September 2013, which were all Android compatible. Google introduced the Android Wear platform about six months after that. All the major Android manufacturers have at least one smart watch on the market, or one on the way (HTC, LG, Motorola, Samsung, etc.)
I think smart watches are cool, but I'm still holding off, they don't seem worth $300+ yet. The heart rate monitors some of them have is good for fitness, but not as accurate as a chest strap. Text messages and notifications on your wrist is kind of nice, but it takes 1 second to get my phone out of my pocket.
I don't wear a watch, so maybe I'm not the target audience for these things anyway.
