That's the picture today with smartphones accounting for 28% of the total phone market. If Apple's market share doesn't keep up with smartphone adoption their profit % will go down. That's simple math. The notion that Apple doesn't care about market share is absurd.
Right, but we have to limit ourselves to the upper segments of the smart phone market. If we include the cheapo Androids when talking about smart phones then Apple's relative market share may very well drop in the coming years (unless they come up with a lower-end iPhone but even a low-end iPhone would probably not exactly be low-end).
But I agree that they cannot afford to lose ground to HTC, Motorola, LG and Samsung's high-end phones.
I don't think you understand the math there. Unless competitors claw their way up to Apple-like margins, market share (or share growth) will decline much faster than profit share will. Even if profit share declines, that doesn't mean that actual profits decline.
