Happy I stuck with my older Samsung dumb TV. Great screen, decent size, flat enough to mount on a wall, and does everything I need it to do regarding hooking up my little i5/8GB baby office PC turned media hub. I don't care that it's only 1080p, looks just fine when I'm in bed and watching movies on it. Even when smart devices were first becoming THE thing to have, the idea of having to download updates for my TV got me thinking about the more nefarious aspects of such tech the future may hold.
I think a lot of it comes down to me just not being very materialistic, or needing my household devices to be internet ready with installed apps and no way of managing permissions or data harvesting. Even my cars are older, and were made well before integrated SIM cards and constant data collection, and I've no plans to upgrade any time soon. I guess I just never 'got' the appeal of having a smart device that wasn't just my phone (and even then, I barely use any apps on my phone outside a web browser (which eliminates the need for most apps anyway) and the camera.)
