I ended up having more than forty interviews and conversations with him. Some were forma ones in his Palo Alto living room, others were done during long walks and drives or by telephone. During my two years of visits, he became increasingly intimate and revealing, though at times I witnessed what his veteran colleagues at Apple used to call his "reality distortion field." Sometimes it was the inadvertent misfiring of memory cells that happens to us all; at other times he was spinning his own version of reality both to me and to himself. To check and flesh out his story, I interviewed more than a hundred friends, relatives, competitors, adversaries, and colleagues. His wife also did not request any restrictions or control, nor did she ask to see in advance what I would publish. In fact she strongly encouraged me to be honest about his failings as well as his strengths. She is one of the smartest and most grounded people I have ever met. "There are parts of his life and personality that are extremely messy, and that's the truth," she told me early on "You shouldn't whitewash it. He's good at spin, but he also has a remarkable story, and I'd like to see that it's all told truthfully."
