There is a lot to be said for comparing [going from mainframes to the PC] to going from trains, from passenger trains to automobiles. And the advent of the automobile gave us a personal freedom of transportation. In the same way the advent of the computer gave us the ability to start to use computers without having to convince other people that we needed to use computers. And the biggest effect of the personal computer revolution has been to allow millions and millions of people to experience computers themselves decades before they ever would have in the old paradigm. And to allow them to participate in the making of choices and controlling their own destiny using these tools.
Steve Jobs, 1990
