I dunno if this is a hot take. I don’t focus on updates. Major software updates generally have new features. Minor software updates are generally security updates or bug fixes. It’s OK for me if the device is in its last lap update-wise. It’s not like it’ll be unusable if there’s no major update anymore. Buy a device for what it is now. If it’ll get 4 major updates, that’s a bonus, not a hard requirement when buying a device.
