Walter Isaacson spent a lot of time with Steve Jobs in preparation for the biography he was writing of the Apple co-founder. As such, he came to intimately understand the man and the perception that people had of him. By that same token, he gained an understanding of Bill Gates as well, as he related on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central).

Just as Apple and Microsoft have become these two opposite giants in the field of technology, so were Steve Jobs and Bill Gates, according to Isaacson. "Steve is very mystical, artistic, sort of comes from the counter-culture," he said. "Bill Gates is awesomely smart ... and makes a great business model for Microsoft, but he never makes the artistic products."

According to biographer Walter Isaacson on '60 Minutes' (Sun., 7PM ET on CBS), Steve Jobs reluctance to be cut open earlier in his struggle with cancer may have cost him that battle. "He regretted it, some of the decisions he made," Isaacson said. "And certainly I think he felt he should have been operated on sooner."

Instead, Jobs went with spiritual treatments and changes to his diet. It took nine months of prodding from those closest to him to convince Jobs to go in for the surgery, but by then it was too late for the procedure to save him.
