Photos: Intel Core 2 Duo launch

Intel President and CEO Paul Otellini stood on stage at the company's headquarters in Santa Clara, Calif., to formally launch the company's most important product in a decade, the Core 2 Duo processor.

Otellini holds up the Core 2 Duo processor, which was built with Intel's 65-nanometer manufacturing technology. It has 291 million transistors packed into an area smaller than the fingernail on Otellini's little finger, he said.
