Now Apple’s chief executive is set to collaborate on an authorized biography, to be written by Walter Isaacson, the former managing editor of Time magazine, according to two people briefed on the project.

The book, which is in the early planning stages, would cover the entire life of Mr. Jobs, from his youth in the area now known as Silicon Valley through his years at Apple, these people said.

It would be a digital book only he is capable of. And I suppose it will be on sale only at iBookstore.
