• Levinson was one of the first people Jobs told about his cancer and his decision to try alternative therapies. Levinson "pleaded every day" with him, according to Isaacson. The fights almost ruined their friendship. "You cannot solve this without surgery and blasting it with toxic chemicals," he told Jobs. "That's not how cancer works."
• On why Jobs waited 9 months to have surgery. "I think Steve has such a strong desire for the world to be a certain way that he wills it to be that way. Sometimes it doesn't work. Reality is unforgiving."
• On why Jobs decided to build a cell phone. "He was always obsessing about what could mess us up." The conclusion Jobs had come to: "The device that can eat our lunch is the cell phone. Everyone carries a phone, so that could render the iPod unnecessary."
• Levinson was among those pushing for Jobs to open the iPhone up to outside developers. "I called him a half dozen times to lobby for the potential of the apps." If Apple didn't encourage them, he argued, another smartphone maker would.
• On the compromise Jobs hit upon: Allow outsiders to write apps, but require that they first be tested and approved by Apple. "It was an absolutely magical solution that hit the sweet spot," Levinson says. "It gave us the benefits of openness while retaining end-to-end control."
• On Jobs' decision to go after Gizmodo for buying the stolen iPhone 4: "He can react viscerally... There is an arrogance. It ties into Steve's personality." Such arrogance was fine when Apple was the feisty underdog, he argued, but not when Apple was dominant in the mobile market. "We need to make the transition to being a big company and dealing with the hubris issue."
• On Jobs' reluctance to respond to complaints about the iPhone 4's antenna. Jobs was in Hawaii at the time, but in "constant contact" by phone with Levinson, who urged a little humility. "Let's try to figure out if there's something wrong."
• At Jobs' final board meeting, Levinson was one of those who spoke, according to Isaacson, praising Jobs' diligence "in assuring that there was a smooth transition."
