The trade show, on Feb. 12-13 at the Sands Expo Center, didn't lack for display screens in ever-larger sizes and configurations, along with image management systems. It also featured most of the bigger brand names in the pack, and plenty of system end-users among the 4,000 or so (not including vendors) in attendance. features
