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."

And then he summed the difference up in an analogy Jon Stewart absolutely loved. He said, "In the end, [Bill] makes the Zune and Steve makes the iPod."
