More than 600 million iOS devices sold, Tim Cook says

Tim Cook is on stage in California right now talking iOS numbers, and as you might imagine, they're big. There are more than 600 million iOS devices sold worldwide, according to Mr. Cook, and almost half of those just since the last year's WWDC. Smartphone usage market share is high, with iOS garnering 50 percent more usage than other platforms, and the iPad is even bigger in the tablet category, with 82 percent of usage as compared to 18 percent of "other" tablets.

Users are also satisfied, with the iPhone winning multiple awards in its lifetime, and boasting a 97 percent satisfaction rate. Users are also unified on a single iOS install, with 93 percent of users using iOS 6, which Cook joked was a far cry from Android's situation. Cook then segued all of these numbers and this satisfaction into the announcement of iOS 7.
