Evolution and extinction
One thing that you could argue is that the constant battle for survival between manufacturers is causing rapid evolution of hardware, just like species fighting over a limited food supply. So if you don't already think that Android is the superior platform, just wait a little more and see what emerges. While Apple, on the other hand, is forced to evolve to compete with everyone else, but the pressure just isn't the same, at least not yet, since they still have their niche carved out and there are no direct competitors making Apple clones.
I'll leave it to others to get philosophical about the intelligent design vs. evolution of a species debate, but the pressures are kind of the same.
