Apple's primary focus is on UX simplicity and Customers couldn't care less how it's implemented behind the scenes, they just want to get stuff done, find the Word document they were working on or see the Photo or Video they just took.
The less Customers have to know about how technology works the happier they are, and the more successful Apple is.
