Among the glut of numbers coming out of the Apple keynote today, delaying the reveal of your next iPhone, was a particularly impressive one: 250 million. That's the number of iOS devices sold. That's 250 million iPhones and iPads in the wild worldwide, running a grand total of 18 billion apps between them, which have netted developers a whopping $3 billion. That ladies and gentlemen, is nothing to sniff at.
