I'm looking for any articles or documents that explain or interpret exactly what part Steve Jobs played in whatever he did with computers and revolutions and such. Was he behind everything that got the computer to the way it is today? Did he single handedly bring the world from CD players to MP3 players? Did he invent the first music player for a computer that stores all your music in it? So coming down to the point.... what exactly did he do? What would have happened if he did not do what he did? Thanks.
