Apple Expo 2003 Pictures
99Mac.com posts photos from the set-up of Apple Expo 2003.
At the Apple Booth, there appear to be iMacs, eMacs and PowerMacs setup, under a sign promoting iChat AV and the iSight. According to the site, closer examination was not possible due to nine guards protecting the booth as well as "secret boxes". The walls are also covered with large black covers.
Another user also posted other photos of the Apple Expo setup.
