I'm on a Steve Jobs kick lately; last week I wrote about how someday there may be statues of him all over the country. I came across this great video of him responding to an insult from someone in the audience at the 1997 Apple Developer Conference, just after he was renamed CEO. If you listen closely, you'll notice that in his response he does far more than respond to the heckler. He lays out Apple's philosophy on product development that would fundamentally drive their outrageous success for the next 15 years.
Start with the consumer. The consumer must drive the technology. It's five minutes long but definitely worth watching.
