I was never wild about the segway, use that 4hp electric on a recumbent scooter on the other hand (talking 50mph now) instead of using it to stand while motionless...
For the same range/speed and lots more portability (carry it like a suitcase) and navigability (much narrower), and a fraction of the cost of a segway, I could see a solowheel, or an airwheel. Plus it has a full wheel fender
