"... That guy was talking about how Microsoft had solved ... tablet computer and they're gonna do it with pens and he just, like, shoved it in Steve's face the way that they were going to, like, rule the world with their new tablets with their pens. Steve ... show them how it's really done ... At that time, touch screen was resistive touch ... He said, "we need to do capacitive-touch and has to be multi-touch." The moment you saw that, you knew this was the way to go."
