How so? I say this as a Pebble user that was thoroughly underwhelmed. There was the marginal benefit of receiving notifications on my wrist, but it was never worth having yet another device to charge and worry about. My watch now sits in my desk drawer.
Personally, I really enjoy the automatic sleep/activity tracking that my Pebble provides (via Misfit app)
Besides that, I mainly use it for "watch" stuff.
That said, it is really nice to be able to get notifications without taking my phone out in certain contexts—bicycling, walking, in a pool, phone charging in other room, etc.
That's your opinion. For me it has been life-changing.
