Attendance at this year's Macworld | iWorld event was approximately the same as last year's Macworld Expo -- about 25,000 people -- according to IDG World Expo, the group that organizes the "ultimate fan event." A wrap-up news release from IDG World Expo noted that about 40 percent of the attendees at this year's event were first-time visitors, which may translate to growth in attendance for next year's event scheduled for January 31 - February 2, 2
