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.
No new phone for me until they make a pixel with a headphone jack
I’m still waiting for headphone jacks to come back. My ancient iPad has one, and everything since does not. Which means when this one dies I won’t be replacing it (decided I will just use only what my laptop will do).
For my iPhone (which is new enough that it doesn’t have a headphone jack, I limit it to just texts and phone calls, and do everything else from my computer or a cheap little MP3 player.
