Including the iPhone in the 4.3 billion worldwide phones is like including PCs in electric typewriter sales; sure they can do some of the same things, but they're clearly different products.
> They have a monopoly on non-horrible smartphones
That's like saying, "Arby's has a monopoly on good-tasting fastfood." You can't have a monopoly on being the best at something. Just because you think that the iPhone is the best phone on the market doesn't mean that you can claim that Apple has a monopoly just because you don't like their competitor's products. (Well, you can -- freedom of speech and all -- but you're wrong)
There's nothing, certainly not any behavior by Apple, preventing anyone from coming up with an equally non-horrible smartphone. The closest they've come is by buying the quantity of flash memory they have.
