I think you are underestimating how much disposable income some people have. People buy skiing equipment for 2000€ Euros just to go skiing a few times a year.

I think you are underestimating how much disposable income some people have. People buy skiing equipment for 2000€ Euros just to go skiing a few times a year. They buy mountain bikes or road bikes for 5000€. They buy brake upgrades on their sports car for 7000€. I think Apple will easily find a few people willing to spend 4000€ on a toy. Whether the market will be big enough for 3rd party developers to be sustainable is another question.
