When I went to Xerox PARC in 1979, I saw a very rudimentary graphical user interface. It wasn’t complete. It wasn’t quite right. But within 10 minutes, it was obvious that every computer in the world would work this way someday. And you could argue about the number of years it would take, and you could argue about who would be the winners and the losers, but I don’t think you could argue that every computer in the world wouldn’t eventually work this way.~ Steve Jobs
