The "Android Is Winning" meme and the Myth of Market Share

First, market share without context assumes that each percentage of market share is equal to another – that every Android activation is equal to an iOS sale. Nothing could be further from the truth. You can’t simply total up market share and determine a winner any more than you could count up coins or poker chips without knowing the underlying value of those coins or chips. A penny does not have the same value as a quarter and only a small child would rather have more coins than fewer coins but more money.

Seems like not a week goes by without someone telling me that Google has a bigger share of the smartphone market than iPhone. I'd love to split a restaurant bill with some of these folks.
