I don't really agree with you. In 2000 Apple gave the world a powerful commercial UNIX workstation OS that "just worked," along with a fantastic IDE and development tools for free. There were lots of things in there for power users that may not have been advertised or easily discovered, but they were there and documented somewhere if you knew how to look.
Now, the workstation OS started going to shit as you described after they moved to intel, supposedly Mavericks fixes that a bit. I don't know, never owned an intel mac (thats also when they started sunsetting hardware almost as quickly as it was released).
Its iOS thats for the lobotomised retarted proto-lifeforms. And, yes, some of that was getting into OSX proper. But I believe the backlash with Windows 8 showed them that might not be too wise and I've heard they've backed off, again, with Mavericks.
