[Op-Ed] Are smart watches worth your time?

Since so much time has passed since the Moto 360 came into my life (including the release of its successor the Moto 360-2 and the Moto 360 Sport) I thought I might skip the straight up review, and instead focus more on the driving question behind this, and other wearables on the market right now: are smart watches a fad, a nice to have, or a must have?  I asked in the title of this article if "smart watches are worth your time" - using a very obvious but still clever pun - and hopefully I can answer this for you, and other folks considering picking up one of a great number of options available today.
