I think this invention has been way overhyped. I also think that in the consumer market it will end up as more of a luxury toy than a replacement for personal transportation. First, what if you need to carry cargo? It looks like you'll have to carry it on your back, so forget a trip to the store. Also, it seems its speeds are only about that of a light jog, so if you need to get somewhere, even if it's nearby, you'll only be able to get there slightly faster than if you walked, which most people won't have the time to take that long to get to their destinations. Third, you won't want to use it when the weather is bad unless you enjoy getting rained on. Fourth, because it won't replace automobiles, it is highly dubious that entirely new roadways will be built for them, meaning that you'll have to use whatever existing sidewalks or bike paths are available, and those aren't always available everywhere. Finally, much like a bike I suppose you'll have to lock it up to a bike rack or something similar when you get to your destination. Then you're risking getting it stolen just like a bike, and I certainly am not keen on getting a $3000 possession stolen as easily as a bicycle can be.
