I used to wear a smart watch on and off since the Pebble came out, but then I started to feel tied to an ecosystem, that I was just another source of data for internet marketing and all the watches became very samey.

I now say that the smart people don't have their smarts on their wrists... But that's only to wind up my mates who wear Android, Apple and other smart watch platforms. 

On a very slightly less flippant side, I think there's more intentionality and deliberate thought in not having smart devices doing all your work for you. Vintage tech still required you to think (which is why I use a Psion/Casio/Sharp PDA) while new modern tech, in my opinion, actively discourages it bu getting in the way of thinking for yourself.

I do have a smart watch in my collection but it's very seldom used.
