I love smart watches! It's been crazy in 2015 and I think it's gonna keep growing. At the moment, smart watches are like smartphone accessories but it will probably improve. Which means that they're not necessary. A lot of people say "why the heck would I want a smart watch" but it's really just for those people who think it's cool. To the general public it sounds stupid.
I'm very excited to see the smart watches of 2016, sounds like hype!
