Vegas gets over 40 million visitors a year. To manage and entertain those streams of people technology certainly helps. I saw a few examples this week.
At SAP’s TechEd, we got a tour using Sennheiser headsets. The one-piece, cable free design was comfortable and has a range of 200 feet, and a battery life of 8 hours. 20 of them can be carried in a specially designed case which also charges them.
