a while back I saw a nice short television interview of him.
I think it was part of this story: [msnbc.msn.com...]
I remember him saying he was concerned about how to make money off of something with almost zero production costs. (additional copies of his software). He decided to give it away. then charge for updates.
I think that worked for him. :)
