I've bought mine 3 years ago, mainly for managing notifications (I was doing business oriented things back then and had a lot of social notifications), and it was immediately worth it : no need to get my hand out of that keyboard to unlock my phone and see a notification I don't care about every 5 minutes (especially frustrating when you're a vim user trying to optimize your hand movement around the keyboard).
Since then, there's three other use cases that make me use the watch every single day for those three years:
* controlling spotify without needing access to my phone when outdoor
* having my up to date grocery list at the wrist any time I feel like shopping (thanks to google keep)
* setting timers through voice control while cooking
That's certainly not as game changing as having a computer vs not having one, but that's still far from completely useless.
* TOTP generator
* Music control
* Notifications
* Emergency light (it isn't that bright, but has saved me a few times when I just needed a bit of light)
What is a pity about all this is how s* bluetooth chipsets and drivers are. At least once a week my phone's BT just glitches off >:|
I do see a lot of them around here (Netherlands), but I do agree that the novelty has worn off.
Well, I find my Apple Watch useful for tracking activity and notifications.
I've found them to be such poor experiences and falling so far short of expectations/hopes/marketing that I went back to using G-Shock. I would be surprised to learn people find their smart watches useful and are still actively using them for anything more than just telling the time (for which they are a chore to constantly charge).
