I got the rents a new iPad for Christmas, so I got their old 16GB Mini 4. I restored with iOS 14.3 and it runs fine. I am a little put off that without installing a single app or anything only 8.6GB are free after a restore, that's 45% of the entire device storage taken up by iOS. It reminds me of Windows 10 on those crappy 32GB eMMC tablets with the OS taking up the entire internal storage.
