Steve Jobs did his last product launch last March, for the iPad 2. At the close, he stood in front of a huge picture of a sign showing the intersection of streets called Technology and Liberal Arts.

It was a lifelong ideal for Jobs, the same one that had drawn him to make his famous 1979 visit to the Xerox Palo Alto Research Center, or Xerox PARC for short. That was where a group of artistically minded researchers had developed the graphical user interface, or GUI, which Apple's developers were to incorporate into the Lisa and the Macintosh a few years later.
