Still getting updates for my 7 year old ipad air 2. About to get ios 14 as well. Android has warped peoples perspectives on how long a device would get updated. On PC you can just keep installing updates until the device can't keep up anymore.
The iPad Air 2 was introduced just under six years ago. But even the original iPad Air, which was introduced nearly seven years ago, still gets security updates. The last update was released less than a month ago. It's stuck on iOS 12, though.
