I’m on my fourth smartwatch. They have gone from being a novelty of some value, to being of value with some novelty.
It means my phone can stay in my pocket or briefcase, with the added bonus of warning me if I’ve left my phone behind as soon as I get out of BT range. I have different watch faces depending whether I’m at home, work, driving or out and about. Each one has different complications on the face to operate things. At the end of the day it normally has 60% battery remaining and just gets put on the wireless charger on the bedside table.
I too, am pretty ruthless with what notifications come through to it. Otherwise you may as well be one of those people interacting with your phone every few minutes.
It has voice assistants (Google and Bixby) that I would only use very rarely. I probably only use half of what the device is actually capable of.
Of late it’s usefulness has increased by installing an app to communicate with my car (easier than fishing out my phone).
I have multiple legacy mechanical watches in my drawer gathering dust. I have no intention of going back to them.
