By the same logic, it would appear that because Apple only produces three desktop models and three laptop models, that it makes no sense to compare market shares of Windows and OS X. Am I right?
There is nothing wrong with the comparison of the market share if you so choose. But the comparison is not very valid, since Apple is not trying to position its operating system onto other manufacturer's products. The article speaks of Androids gain in a market share race that Apple is not running in. Thus the point of my post.
If Apple provided its OS to Samsung, Motorolla, LG group, HTC Corporation among others and was now losing share to Android on those same platforms, then the article would be statistically relevant. Apple is a hardware company first, for which they provide their own software. So the articles comparison of Android market share versus iOS 4 is really not very relevant. Apple is not in a license race to distribute its software to take market share from Google.
The iPhone, as a piece of Hardware, has out sold every other smartphone on the market, including any individual Blackberry product or any individual Android piece of hardware. That is Apple's race, and they are still winning it, by a comfortable margin.
And in your comparison of Apple's computer lineup, it has a very substantial and growing share of the market when compared by manufacturer. Again, if you want to compare Apple market share versus all others, feel free. But it is not a competitive measure of Apple. While they only have nearly 9% of the market share of all PC's, they have 91% of the market for ALL PC's sold with a price of greater than $1,000. Comparing the OS however is irrelevant. Apple doesn't sell it's OS as an install option on other PC's so why is a comparison versus Windows market share relevant? Apple again sells hardware. It sells more PC's than Sony (another high-end PC retailer) for example. I don't think BMW is worried about selling fewer cars than all other auto manufactures combined either. There is a reason why Apple's market Cap is greater than Microsoft's. That is because they realize that controlling 90% of a high-end, high-profit market is far more important than controlling a less than 10% share of the budget-ended, low-margined, "crap" market.
