I don't want to derail this thread due to a passing mention of Edison's name, but.

Edison's major inventions represented a difference in kind, not in degree, that drastically changed things for humanity. Think of how different life is as the result of recorded sound, the concept of an electric company or light bulbs for home use.

Job's products were often well designed incremental changes. Apple made computers consumer friendly, but they didn't invent the technology. They didn't invent the global telecommunications network that makes the iPhone useful either.

Edison was an Inventor with a capital I. Jobs was a truly great corporate executive.
