For example, I only buy/use old high-end (for their day) business class laptops and put linux on them. They work for everything I need to write and surf.
I also bought an iPhone that was already a few years old and plan to keep it until it stops getting security updates from Apple. I also moved from Android to Apple not because I like iPhones better (I don’t, really), but because the years of security updates (versus maybe one or two, on Android) matters to me.
I want to upgrade my basement TV which is now 15 years old but the picture quality is fine at 720p/1080i and it has no problems. Its a Samsung along with the 8 year old one in the living room. No smart features or internet connections.
Years ago (before any TVs were “smart”) I bought a high-end, brand new Samsung TV that turned out to be a piece of junk. Samsung wouldn’t honor the warranty, and was just a ass on their customer service (I’ve refused to own or buy anything Samsung, ever since), and a local TV repair guy I paid too much money to couldn’t fix it. So I junked it and bought an off-brand mid-range TV that I’m still using now after maybe 15 years? When it dies, since I refuse to own a “smart” TV (and they are all “smart” now), I’m going to replace it with a big dumb monitor, a little computing box good enough to run streaming services off the web, and a wireless keyboard, -or-, just buy non-smart TVs at garage sales.
Yeah aside from a few “hospitality” models of TVs they are all smart. My plan is to buy a smart TV and never connect it to the internet. We have a latest gen AppleTV box in the living room that works great.
