It's the very significant market share of "The Others" that explains why Apple, and with them OS X, will never become a mainstream player. Apple does not play well with others, and they do not want to have Hackintoshes on the market. But people, obviously, want to use customized and self-assembled "other" hardware - hardware that fits into their budget.
I would rather like to see a number of how many of those Apple machines also have a copy of Windows on them. Has Microsoft already reached the 100% mark by now?
And that's related to this thread how?
I, for one, very much like the fact that Apple doesn't have a market majority. When you have a large user base, you can't cater for everyone. How lovely were the days when the only people using Macs were graphic designers and desktop publishers, allowing Apple to make their computers tailored to the users' needs.
