7.4% of the worldwide computer market is hardly rounding error. Lenovo/HP/Dell put together account for a hair over 50% of the market, although it wouldn't surprise me if the total profits from Apple's 7.4% were greater than the total profits from the top three's 50% due to significantly higher margins. By comparison, that's roughly equivalent to Honda's market share in the automotive industry, and I don't think anyone would dismiss Honda's sales as being a rounding error. Other than that, I agree, they are clearly not the sort of company that would be interested in selling chips to other vendors, at least based on their history up to this point. If there were to start selling CPUs to others, it would not be playing to their strengths and would be a huge departure for them as a company.
