I don't like Windows 8 either but at least it's still windows.. the MAC OS X isn't even really an APPLE OS anyways. It is UNIX kernel with a mac style gui.
I prefer Windows 7 or Linux myself.
I'm not sure I understand your point. Are you saying the UNIX kernel is somehow inferior because Apple didn't develop it?
It seems to me that the UNIX kernel is a very solid operating system, and Apple didn't see any need to invest considerable resources to develop their own kernel and realize marginal improvements (if any).
