More generally, I made an effort to leave out things that weren't relevant to the main narrative themes of the book, namely that there were two sides to Steve Jobs: the romantic, poetic, countercultural rebel on one side, and the serious businessperson on the other.

When there are multiple versions of a story, you really have three ways to go. You can pick the most sensational version. You can try to balance things in your gut to get to what you think is the honest truth. Or you can err on the side of kindness.

I visited Jobs for the last time in his Palo Alto, Calif., home. He had moved to a downstairs bedroom because he was too weak to go up and down stairs. He was curled up in some pain, but his mind was still sharp and his humor vibrant.
