In the Matt Damon sci-fi flick Elysium, the wealthy have smart watches not unlike 's. Perhaps there is one use to the smart watch. When you're at a party, as many know, you'd probably be checking your phone every 10-20 minutes or more at a time. If there's an emergency, the smart watch is perfect for that type of alert. Now that I think about it more without digressing too much, (I may expand on this in another thread) we could be moving towards phablets replacing tablets and smart watches replacing phones.
