Mr. Jobs didn't invent things. He marketed things.
To his credit, he hung out with some very smart people, and then hired them, once the company was started.
Who invented the Mac? Jef Raskin,George Crow, Chris Espinosa, Joanna Hoffman, Bruce Horn, Susan Kare, Andy Hertzfeld, Guy Kawasaki, Daniel Kottke, and Jerry Manock.
Who invented the ipod? You have to credit Jon Rubinstein, who brought a really tiny hard drive back from a business trip to Cannon Ltd in Japan in the mid 1990s, circled his engineers around him at FirePower systems, and asked, what can we do with this?
And the ipad? Well, the GridPad and the EO were there long before the ipad.
