You must have missed the part where I wrote as long as you have a sustainable position.

In the case of Apple vs Samsung, the smart phone market is at a different level of maturity that lack of market share is not going drive developers away from iOS, but if we were much earlier in the market then it would be a significant issue for them.

What's Samsung's story?

I don't know what sort of margins Samsung is making on their devices, but they don't have to make as much per device as Apple to still be a success.
