Eh, smartwatches are actually useful though - while I don't use them a lot for "phone replacement," I do use them for a lot of things they do really well, namely checking the time(lol), as well as health tracking. My watch constantly tracks my heart rate, any variations in it, as well as a bunch of other data, including sleep.
I don't need to manually adjust workouts, runs, or walks either. When I work out, it is decently accurate in tracking those too.
the other day it actually woke me up because my heart rate had dropped dangerously low. So, useful there.
Other than these, a lot of "doing stuff on watch" has been replaced by the RayBan Meta smartglasses for me tbf.
