There is a (apparently) small group of people for whom the Segway is valuable. For the rest, a bicycle is superior, and even there, the new electric bicycles with motors in the hub solve at least one of the same problems as the Segway - power assist. The whole "balancing on side by side wheels" thing is cool looking but offers little to no value for most, increases width which is a disadvantage in urban areas, and consumers have spoken with their locked wallets.
