The 2011 Macworld Expo brought a modest increase in exhibitor numbers since the 2010 show, but many people were waiting to see the crowd sizes before gauging the show's success. The lobby of Moscone West was packed with attendees waiting to get in on Thursday morning, making for a show that became more and more crowded through the week. By Saturday morning, it became difficult to wade through the packed halls. MacNN put together a gallery of images from some of the interesting sights at the expo.
