Hardware is one piece of their strategy, sure. But Apples primary business is selling the end user experience.
That's why I guarantee Apple doesn't talk about any of the things in your post. Your in the techie weeds. Apple knows that if they delight their customers, all of the stuff you are focused on will take care if itself.
This is why its so hard for other tech companies to compete with Apple. They focus (like you) on the tech and all the little moving peices, while Apple focuses on the end user and their ultimate use of the products.
