I go with 200 - 250 Euro phones. The oldest surviving one is from 2016, stuck at Android 8. I use it as backup and as GPS tracker / navigator on my bicycle because it's small. The recent one is from 2019, Android 11 and still getting security updates. I don't know for how long it's going to go, but 70 Euros per year / 6 per month (going down) is OK. Of course I'd prefer to see it going on forever. My laptop is from 2014 and sooner or later it will die either because of lack of spare parts or because NVIDIA won't release a driver compatible with my card AND newer Linux kernels. Who knows if I'll be able to use Noveau by then.
