Anyway, Apple has always had a disproportionate share of any market it seriously participated in — the big difference is that 10 years ago Apple was a very small part of a single market. Some fluctuations will probably happen over the next half a decade, but you can bet that Apple will remain absurdly profitable in a way that embarrasses most of its competitors. It's just something that Apple is good at.
I'm betting it's not. It's something Steve Jobs is good at.
