I'm not convinced that to the average buyer there is enough separation there any more to call them separate markets. I know several people who have bought Apple machines recently because they pretty much wanted "a computer" and as far as they were concerned the Apple machines were better enough than the alternatives to justify their higher price. It running OSX was a point of difference but only in the way that people buy eg. a Dyson rather than some other no-brand vacuum cleaner, not like a decision to buy a car instead of a motorbike.
Dell probably would love to have Apple's revenue share, but they don't have Apple's requirements for style so would make a hash of it. Theirs would also end up being plastic instead of carbon fibre.
