I find it hilarious that MacRumors members can turn the least controversial topics into an argument. Are you guys being serious right now?
It's very impressive that Apple, a company that exclusively sells high-end smartphones, is in the top five. Stop trying to make excuses for why it's not number one, because no one expects it to be.
Some people seem to fail to make the distinction between smartphones and dumbphones. Samsung, like Nokia, sells crap loads of dumbphones. (Which is not a bad business model, like a lot of people in this thread seem to be suggesting; it's just a different business model.) I'm not sure if a lot of you guys realize that Samsung's product line does not comprise solely of Galaxy S's. This chart is not a measure of Apple's (or other smartphone makers') success, because it's analogous to comparing the number of economy class tickets sold by an airline to the number of private jet rentals sold by another.
