Apple is definitely ahead of the curve even on iOS devices. I'm uncertain about the latest iOS update, but the one before supported iPhone 4s devices, that's 4 generations ago. None of the updates was paid. All older devices still work with the versions that you have. Compare to any kind of android devices: They rarely get obsoleted by OS Updates since there are none. Edit: My Macbook Air 2nd gen (2010 (?), can't really remember) still runs El Capitan. It's getting a bit limited in what you can do on it, but it's fine for browsing and lightweight work. Obviously no gaming :)
