Videos: Jobs shows off Intel-based iMac and laptop

At San Francisco's Moscone Center, Apple Computer CEO Steve Jobs debuted an updated iMac.  The machine sports the same sizes, same design, same features, and same prices as the Power PC-based iMac. What's different? Jobs said it will be two to three times faster because it uses Intel's dual-core Duo chip.
