> By contrast, one of my old iPads is thinking about enrolling in a job retraining program to learn to be a trivet. This despite all of its components being in perfect working order. I have an iPad Air 1, a device that is pushing ~5 years by now, that became abhorrently laggy with the transition from iOS 10 to iOS 11. Sliding up the multitask view or sliding down the cover sheet usually hovered around 5-20FPS, and sometimes came with a 1 second (!) delay. I don't know what magic the iOS devs worked with the upcoming iOS 11.3 (I run the beta) but both actions are fluid now, and the delay is gone. Besides that, my parents have an iPad 4, which is 'stuck' on iOS 10 but still is incredibly smooth and, so far, works perfectly well with iCloud. I used to think that Apple didn't mind old devices being bogged down with big updates, since the unintended side effect would be people pushed to newer devices. However, with techniques like App Thinning, the way the 5S became smooth again going from iOS 9 to 10, and now the way they revived my iPad Air I'd say they seem to be reasonable in choosing when devices are too old and holding back iOS as a whole. Hell, with Apple your iOS device gets 4-6 years worth of big updates.. with Android, you're lucky if you get 2.
