Photos: Building a Macworld

Setup is under way for next week's Macworld Expo at the Moscone Center in San Francisco. As you enter the South Hall and head downstairs to the show floor, you'll be reminded that something's in the air. Is it some new wireless gizmo? An updated MacBook or iPhone? Or perhaps a whiff of the rotting stock market? Either way, Apple is kicking off what should no doubt be another interesting year.
