Apple is definitely ahead of the curve even on iOS devices. I&#x27;m uncertain about the latest iOS update, but the one before supported iPhone 4s devices, that&#x27;s 4 generations ago. None of the updates was paid. All older devices still work with the versions that you have.<p>Compare to any kind of android devices: They rarely get obsoleted by OS Updates since there are none.<p>Edit: My Macbook Air 2nd gen (2010 (?), can&#x27;t really remember) still runs El Capitan. It&#x27;s getting a bit limited in what you can do on it, but it&#x27;s fine for browsing and lightweight work. Obviously no gaming :)
