I think you'll find that the effort is measurable, and not subjective. How can you possibly argue that the army of programmers Apple has devoted to working on this one stack in one domain do less work than the widely distributed work done by a far smaller number of programmers on a far larger number of desktop stacks? Don't be ridiculous. I didn't say that the outcomes were better, just that more effort has been put in, in terms of hours-of-human effort.
