I don't think so. I saw this thing in person today and it is indeed VERY COOL !! It is one of those things that really impresses you when you see it operating in person. Seeing Segway operate on video doesn't really do it justice. When adults get on it they become like joyful little kids with a new toy. IT is fun.
Ultimately, it will have to come down in price (say $1500 to $2000) to gain wide popularity but I predict it will and we will see these things all over the place in about five years.
Truer words were never spoken.
