FORTUNE — It’s often been said that Android’s share of the U.S. smartphone market has come chiefly out of the hides of Research in Motion’s BBRY BlackBerry and Microsoft’s MSFT Windows Phone, but nothing shows this quite as clearly as Horace Dediu’s charts at Asymco.com. Not that Apple AAPL hasn’t been hurt by the success of Google’s GOOG mobile platform. Some of the customers who bought Android phones are customers who didn’t buy iPhones.
