In the new issue of Fortune, Managing Editor Andy Serwer interviews John Huey and Walter Isaacson – the biographers of Sam Walton and Steve Jobs, respectively – on Walton and Jobs.

Here are a few highlights from the conversation about Apple and Steve Jobs:

• Walter Isaacson: “I think I understood everything about Jobs except for why he opened up so much.”

• On why he did reveal so much, Jobs told Isaacson: “I have an amazing life. It was very interesting. I just think people ought to know.”

• Isaacson: “Steve was focused on product and did not focus mainly on profit… He was motivated by making the most beautiful products he could imagine. He never wanted to compete on price or be a commodity… For his store he took out a design patent on that staircase, and his name is on that patent, and most of the major Apple Stores now have them. He said, ‘You want that stairway so people believe they’re in someplace magical.'”

• John Huey: “Walter made a joke about Ben Franklin and Einstein and Steve Jobs, but I don’t really think it’s a joke. I think they were all geniuses.”‘
