Not sure if this is good or bad, but it's certainly unusual, and it's part of the reason that this "monopoly" question is sometimes confusing--Apple makes by far the most profit despite also selling the highest-end product, and their unit sales, despite being somewhat less than Android, are still in the same ballpark.

The vivisection of the PC division, the semiconductors, iOS, iPhone, and iPad into separate companies would be deeply satisfying.
Shareholders might actually applaud the results in the end.
