The annual Macworld Expo kicks off this week with Apple CEO Steve Jobs delivering his annual keynote on Tuesday. Show organizers say there was a 28 percent increase in pre-show registrations over last year's show and have added a new “Digital Lifestyle Experience”, expanding the show into the North Hall of the San Francisco Moscone center. Hundreds of new products are expected to debut, and the exhibit hall will feature almost 400 companies serving the Mac community. The Expo also includes five days of educational content for Mac users of varying levels and backgrounds. On-site registration for exhibit hall access is $45.
