Late, great Apple cofounder Steve Jobs topped countless best-seller lists with his gadgets, and now his life story has proved to be a white-hot product as well. Biographer Walter Isaacson, who gained unprecedented access to Jobs, unearthed new details about his feuds with competitors, bizarre self-treatments for cancer, and plans for future devices. And these buzzworthy revelations continue to feed book sales: An Amazon rep predicts that Steve Jobs is on track to be its biggest-selling book of 2011. The one thing Isaacson did not catch? Jobs’ final words, which, according to his sister, author Mona Simpson, were ”Oh wow. Oh wow. Oh wow.” Clearly the world is pretty amazed too.
