No, and unless I have to some type of on-call job in the future, I never will. POTS works fine for telephony, and my computer is much faster, has better features, is far easier to read, and isn't de facto controlled by Apple|Google.
While portable devices can be a useful tool, far too many people are addicted to the dopamine hit they get by hitting "refresh", and/or distracted by shiny tech baubles.
Good on you. I've gone back and forth between having a smart device and not, and while I've been on the move for a while and thus benefitted from having one, will likely go back to pre-smartphone hardware once settled.
Other than net browsing (which I find woefully underpowered on mobile even today) and listening to music, I rarely if ever use this thing's auxillary functions. Most of the "defaults" are just clutter reminiscent of the pre-smartphone vendor days (complete with the "but look, you can make them less visible, just move them around!"). Can relate on the distraction bit as well, as that used to be a bigger problem for me.
