9to5mac points us to a GigaOm interview with computer and GUI pioneer Alan Kay that says:

“When the Mac first came out, Newsweek asked me what I [thought] of it. I said: Well, it’s the first personal computer worth criticizing. So at the end of the presentation, Steve came up to me and said: Is the iPhone worth criticizing? And I said: Make the screen five inches by eight inches, and you’ll rule the world.”

Just under 2 hours and they'll take their shot!
