I have a Samsung tablet that no longer receives updates and it's the only device of this type I've owned for years which operates at exactly the same performance as when I got it. I literally have no reason to upgrade it; all the apps I want work and get updates. My old iPhone 5 started with iOS 6.0 and went all the way to iOS 10 but got noticeably less performant with each new major update. I'm certainly not arguing those updates were necessarily bad but I think it's worth discussing. Security and bug fixes are tethered with changes designed for much more powerful hardware.
