The evergreen question of "how do you go back and/or close an app on IOS?"
Maybe just the circles I run in but these are not evergreen questions in my experience. I don't even know what "go back" is supposed to mean here, or for that matter what it would mean in a Windows application. Is there a system level "go back" in WinAmp/Excel/SimCity/Photoshop I've never seen before?
I feel that some people are just too old to get used to the swipe based ui. I mean friends of mine who just keep buying the only phones with (screen based) back and home buttons.
It's still easier than Windows CE though.
This one caught me completely off guard when opening YouTube the first time on an iPad: Accidentally clicked on a wrong button and got stuck in a "please subscribe to premium" modal. No amount of swiping or tapping outside the popup would help, only thing left was killing the entire app.
This experience put a major dent in my perception of the "Apple has the most intuitive UI" narrative.
