I have a Segway and it is a pretty cool machine. It is hig on technonlogy and it works. I can easilly ride 5 miles into town and back on a charge (5 miles each way).
This prodict has possibility but cost and its ability to operate utside the electronic network will be a factor in its sales. The one-person segway has never caught on, primarily due to cost, I think.
Picture yourself camping on the outskirts of the WalMart parking lot and riding this up to the store.
AND, I don't think it will tow a Scamp
