It was a late morning in the fall of 2006. Almost a year earlier, Steve Jobs had tasked about 200 of Apple's top engineers with creating the iPhone. Yet here, in Apple's boardroom, it was clear that the prototype was still a disaster. It wasn't just buggy, it flat-out didn't work. The phone dropped calls constantly, the battery stopped charging before it was full, data and applications routinely became corrupted and unusable. The list of problems seemed endless. At the end of the demo, Jobs fixed the dozen or so people in the room with a level stare and said, "We don't have a product yet."

The effect was even more terrifying than one of Jobs' trademark tantrums. When the Apple chief screamed at his staff, it was scary but familiar. This time, his relative calm was unnerving. "It was one of the few times at Apple when I got a chill," says someone who was in the meeting.
