And the reason is simple: Steve didn’t just read a script for the presentation. He’d been telling a version of that same story every single day for months and months during development—to us, to his friends, his family. He was constantly working on it, refining it. Every time he’d get a puzzled look or a request for clarification from his unwitting early audience, he’d sand it down, tweak it slightly, until it was perfectly polished. It was the story of the product. And it drove what we built.
