Apple has simply chosen to use them as additional forms of persuasion.

Apple was also on the scene then, but chose to keep their Operating system a proprietary one.

In the past decade or so, when Apple has chosen to tackle a problem, it's done a pretty damned good job.

Apple has simply chosen not to recommend that practice.

Apple made its decision about its design priorities, and chose not to.

Both sold music, ultimately, but Apple choose a far wider unit.

But to me, the more interesting question is why Apple has chosen to (mostly) ignore the enterprise market for so long.

Thinking about it, that may be why Apple chose the $30 price tag.
