We don't see many starter guides for Android to iOS or other OS conversions, but we absolutely should. Vast swathes of user interfaces are non-intuitive to the point of new users not knowing that options exist. Look at one in the Linux group - Ctrl + Alt + F* to get to a console isn't intuitive in the slightest when you're coming from WIN + type "CMD" + Enter.
I haven't had any luck finding a tunic made by Hanes on Amazon, anybody got a link?
