Steve jobs is right because as he's said numerous times, he doesn't give a shit about market share, what he gives a crap about are profit share and making great products, I suspect the latter is primarily to ensure the former.
The low end of Apple's products are last year's model. With 3 generations going they don't need to make 'low-end' hardware, Moore's law takes care of that for them.
"If you went to BMW and asked them why they donit outsell the Ford Taurus, they would say they donit want to make that sort of car," says Mr Jobs. "Apple has 25 million customers around the world, and our goal is to give them the best personal computer that we can, with the best operating system and some of the best applications."
I suspect that you have it backwards. Making great products comes first. Profitability validates that, and makes it possible to keep making great products.
