Obviously not important, but I do still own an iPod Touch 7th gen (released 2019) running iOS 13.7 which I use for reading news sites etc.
I happened to notice Orion – 1.3.8 (13) – was still available for iOS 13, so I downloaded it out of curiosity to see how it coped. It crashes on pretty much any website (with exception of one or two very light, text only ones), I'm guessing because it runs out of memory? (Very occasionally you can relaunch it and it'll show the previous page is was attempting to display, but as soon as you migrate elsewhere, it'll crash again.
The iPod Touch can run iOS 14, but I'm not upgrading to that because common consensus is it ruins the battery life.
