A booth on the show floor–presumably Apple’s–remains covered ahead of Jobs’ Macworld Expo Tuesday keynote speech.

During his Macworld keynote, Apple CEO Steve Jobs shows off the MacBook Pro, an Intel-based laptop that Jobs said is four to five times faster than the Powerbook G4.

The MacBook comes with a breakaway magnetic power cord, pictured here during Jobs’ address.

When Jobs started discussing the transition to Intel chips, Intel CEO Paul Otellini jumped onstage in a chipmaker’s “bunny suit.” “Steve, I want to report that Intel is ready,” Otellini said, handing over a silicon wafer.

This year, Apple Computer celebrates 30 years, a fact that Jobs (pictured right, with Apple co-founder Steve Wozniak) noted in his Macworld keynote.

The new iMacs will go on sale on Tuesday, Jobs said. He also said that Apple will transition its entire product line to Intel chips during this calendar year.

Jobs announced a new accessory for the fifth-generation iPod that acts as both remote control and an FM radio tuner. The product sells for $49 and is available now.

The company has sold 850 million songs, Jobs told the crowd.

Jobs talks about updates to iMovie, another component of iLife ’06. Among the new features are exporting projects to the iPod, video podcasting and the ability to have more than one project open at a time.

The newly unveiled MacBook Pro is an inch thick and weighs 5.6 pounds.

The MacBook Pro is the first Mac notebook built on the new Intel Core Duo, which is actually two processors (up to 1.83GHz) engineered onto a single chip.

During his Macworld keynote, Job flashed specs for the new 17-inch iMac on a giant screen.

The audience was seated at Macworld Expo 2006 in San Francisco just before 9 a.m., when Apple CEO Steve Jobs took the stage to announce the company’s new products.

As the iPod continues its popularity surge, more and more companies are jumping onto the accessory bandwagon. At Macworld, JBL showed off its “JBL On Time,” a $300 gadget that serves as iPod charging base, speaker and dual alarm clock.

Start-ups continue to eye the iPod accessory market, including Atlanta-based Case-ari, which showed off a line of leather cases at this year’s show.

Once-small accessory makers have a big presence at this year’s Macworld Expo. XtremeMac, for example, has a huge, 1,600-square-foot spot right near the entrance to the show floor. It is a stone’s throw from the well trafficked Apple booth.
