You got something that turned out that you enjoy and has a killer app for you.
A week or so ago, there was an article about GPS in cars being something that most people don't like - personally I love it and I would never own a car without it.
Everybody loves something different and there is enough different things out there for everybody to find something that they can't live without. Without being ironic or facetious, it really is a great time to be alive.
I think what the article is pointing out (and was noted in other posts) is that the smartwatch market is now saturated with people who love it and, as they last a few years, there is considerable shrinkage in the market.
