Again from Emotional Design, this time on the ubiquity of cell phones:
I once attended a meeting at the Vatican where I was part of a scientific delegation presenting our findings to the Pope. Cell phones were everywhere: each cardinal wore a gold chain upon which was hung a gold cross, each bishop had a gold chain upon which was hung a silver cross, but the head usher, who seemed to be the real person in charge, wore a gold chain upon which was hung a cell phone. The Pope may have been the center of attention, but I heard cell phones ringing constantly throughout the ceremony. "Scusi," they would whisper into their phones, "I can't talk right now, I'm listening to the Pope."
