Doesn't take much to piss you off, huh?
I'm not saying they are that incredibly different, but I can still see some rare cases, where this case (see what I did there?) can be of some use. Similar to BootCamp on macOS - if you have an app that you need that only runs on Android or something... Though I can't think of what that'd be - though I have plenty of examples of the reverse, so maybe if you're an Android person who needs an iOS app? I don't know - I'm sure there are someone out there who'd be happy to have it though. Not for the average Joe, but you know
