I don't know, iOS was doing a lot of these things before Windows 8 was even in the earliest of pre-release states. Sure the flat UI thing could be argued to have inspired some of Apple's later work... but I think the lack of discoverability started at Apple and was inherited by Microsoft, not the other way around. You are definitely right that it has gotten worse in OS X overtime though...
