Speculation Apple planned to adopt Intel processors had reached fever pitch when Jobs took the stage in 2005, but many didn’t quite believe it. "Now, let’s talk about transitions," Jobs began, opening that year's WWDC. "…Yes, it’s true, we are going to begin the transition from PowerPC to Intel processors."
Jobs pointed out that PowerPC had been unable to ship a 3GHz Power Mac or create a G5 MacBook Pro. News of the transition led to the classic moment the following January when Intel’s then CEO, Paul Otellini, emerged in a cloud of smoke while wearing a protective outfit to join Jobs onstage to say Intel was ready to ship chips for Macs.
