I don't like the Apple watch because of the alerts.
I wish it had geofencing and other custom rules so I could say "give me these notifications all the time, and these other ones when I'm away from home, these when I'm in the office", etc.
Otherwise every notification I get during the average workday happens on my Mac, my iPhone, and my Watch at the same time. It's like sensory overload making every little thing seem like an emergency. So in conclusion I really don't enjoy the ding ding ding of my watch all the time. It makes it extremely hard to disconnect when even your watch is harassing you. I tried turning off all notifications, but then it's less functional than a normal watch.
The new DND custom features are almost there. Maybe in a couple years...
I'll admit it was nice when I was biking 40mi routes regularly or running for use with Strava or something, but I can just bring my phone...
Also trying to do any input on the watch is so painful.
Idea is great, execution is still so far away from where it should be.
