Apple has added full screen app support only recently

I read somewhere that the reason Apple finally added full-screen support to macOS (back then OS X), wasn't because of the Windows switchers. It was to get a bit more real estate out of the MacBook Air's small screen size.

I think it was also to try to get some i(Pad)OS users back to the Mac—one of the major advertised things about OS X Lion (which introduced full screen) was all the iOS stuff they were bringing "back to the Mac".
