Well, the obvious problem is that you could buy four motor scooters for the price of one of these, or God knows how many skateboards, so you have to ask yourself, what's the killer ap for this that makes it worth dropping 5 grand? Most handicapped people with trouble walking can't stand easily either, so that's out. Mailmen wouldn't need it much except for places they couldn't get the truck close enough to to easily walk, and how many places like that are there?

It's possible there's a niche for this, but it will probably be so isolated it will be like the niche for airboats in getting around swamps.

What I see maybe happening is the gyro technology being used for something else.
