The technology is migrating into wheelchairs, which is where it's really going to be amazing. I saw a thing on Dateline NBC last night about the prototype wheelchairs that normally rolled on four wheels but could balance on two, and in the process elevated the user to what we would consider a normal standing height. The balancing system was so good that one user caught a 25lb. weight tossed to him without toppling over, and he played catch with his kids.
