"Because most computer operating systems don’t organize things this way, accomplishing simple tasks can be extremely confusing for casual computer users;" You can't compare an operating system with an application. I can use iTunes on any OS to play my music (the iPhone is nothing special in this regard). iTunes only knows about music, so all the files are "songs". I can consume any song this way on my PC. And as long as all you do is consume, this interface works beautifully. But try creating a song, and suddenly you need to know how things work in a little more detail. Files are not going away, but if all you want to do is consume content, then there are some pretty good apps out there that present your data in intuitive and meaningful ways.
