I love mine. It nags me about exercising, which I need, and then tracks the exercise (with heart rate). It’s convenient to have time/weather/alarms/quick glance at email/messages on my wrist. Paying for things by waving my wrist at the sensor instead of digging cards out of my purse is awesome. And I’m one of the people who had their watch save their life (or at least catch a potentially very serious issue early). It detected a heart problem last year that ended up requiring surgery. I wouldn’t have noticed (well, until the potential heart attack or stroke) without the watch telling me there was something wrong with my heart rate. So I’m a big fan of smart watches.
