I'd agree with all of this, and go one step further to say that it's bad for Apple in the long run that he's such a good numbers guy. He's making great decisions like buying Beats that will make them a ton of money. and he cuts corners in annoying ways that won't stop the average person from buying Apple, like 16GB iPhones and soldered RAM and 5400 RPM hard drives in $1500 computers. So Apple's new products are meh while the old ones are being made actively worse. And all the while he's turning out massive profits, so he's not going anywhere anytime soon.
If Tim Cook had been the CEO when the iPod was released, it would have 500mb storage or something like that, and the same price. And underpowered hardware.

And most people would cheer here anyway because it has better user experience (tm).
