The price is what the market is willing to pay. Not the actual cost of the physical components. Pricing has always been like that. The market just isn't always willing to pay huge margins. With Apple they do.

> give you the best experience

Hardly. For practically every normal user, the best experience is when they don't have to think about hardware or specs at all, forever. Doesn't just apply to computers either. If anything, people doing the things they want with the hardware not existing at all, that would be even better since they didn't want to deal with it in the first place. Reality is of course that the things they want to do are implemented in software, and software runs on hardware. And they still would rather have it not exist, and not think about it. And anything you do that forces them to think about it is a detractor, even if it was "The Right Thing".

It's why Android beats Windows, and mobile devices like phones and tablets beat PCs; there is a whole lot less dealing with the details of the hardware and the software, and more "doing what you intended to do", whatever that might be. Even if the hardware and software is almost universally worse (at the very least somewhere until desktop-class ARM came around).

As far as all your other concepts, reality says the thing Apple does in the Apple way makes them more money than everyone else. So either they are already doing the things you want them to do and they work, or they are not doing the things you want them to do because they don't work to generate the same concentration of money (which is what they exist for, as I already wrote).
