Just cause he died? I was listening to Howard Stern, he literarly thinks that Steve Jobs personally invented the mp3 player and the touch screen. The touch screen in my Nintendo DS and pocket PC both in 2004 were invented by Steve Jobs. That's the reality for so many.
Henry Ford didn't invent the car, he just got it right and made it affordable to the masses.
We techies know better about invention and mainstreaming, but as is the case with just about everything he touched, he revolutionized something that already existed and used them in new ways.
