IDG World Expo today announced a new line-up of presentations to be held on the exhibit floor at Macworld Conference & Expo in Boston this summer. IDG says the “Geeks & Gadgets Stage will feature real-world Mac users who have done extraordinary things with Mac technology – from building “smart homes” to uploading content from a base camp at Mount Everest.” The Geeks & Gadgets presentations are open to all attendees at Macworld Conference & Expo, which will be held July 12-15, 2004 at the new Boston Convention & Exhibition Center (BCEC).
