I loved the DevNet zone. So much to learn. I would like to see more haptic experiences in the booths though. Physical computing, toy trucks, simulated water breaks etc. Many CISCO attendees are used to boxes/appliances and I think it's easier to have us associate with software if it's made haptic. There are some good executions on it already, the car racetrack, the foosball table, etc. They attract visitors. All booths should relay back to the physical world.
