A couple of years ago I literally ran into “Woz,” Steve Wozniak, the inventor of the Apple II and co-founder of Apple Computer, while wandering in one of the geeky electronic parts shops in the bowels of Silicon Valley. When I realized whom I had almost accidentally knocked over, I squealed like a child, even though I was 46 years old at the time and well out of diapers. I can only imagine the self-humiliation I would have experienced if I had accidentally bumped into Steve Jobs at the farmer’s market in Palo Alto. I probably would have needed diapers.
