“In just three years, the revolutionary App Store has grown to
become the most exciting and successful software marketplace the
world has ever seen,” said Philip Schiller, Apple’s senior
vice president of Worldwide Product Marketing. “Thank you to all
of our amazing developers who have filled it with over 425,000 of
the coolest apps and to our over 200 million iOS users for
surpassing 15 billion downloads.”
An interesting number in there: Apple is claiming “200 million iOS users”. At WWDC they claimed to have sold over 200 million iOS devices, but devices and users don’t correlate one-to-one — some people own multiple (or like in my case, many) iOS devices, and some iOS devices (especially iPads, I bet) are shared by multiple family members.
