Just over a month before the first iPhone was to be released in 2007, the authors report, a frustrated Steve Jobs summoned his senior team.

Steve had been using a prototype iPhone for a few weeks, carrying it around in his pocket. When his lieutenants were assembled, he pulled the prototype out of his pocket and pointed angrily to dozens of scratches on its plastic screen.

People would carry their phones in their pockets, Steve said. They would also carry other things in their pockets--like keys. And those things would scratch the screen.

And then, with Apple just about to ramp up iPhone production, Steve demanded that the iPhone's screen be replaced with unscratchable glass.

“I want a glass screen," Steve is quoted as saying. "And I want it perfect in six weeks.”
