The triumph of DOS was the licensing, not the technology itself; that's what made Bill Gates so rich. Even by contemporary standards MS-DOS was a half-assed operating system full of design flaws. Saying that Kildall made a much better operating system misses the point. The operating system is not what made the money; Gates could have sold practically any OS with his licensing deal and made the same fortune. He literally sold the license before he even owned DOS.
