It'd probably be really heavy to pick up, and hard to maneouver in situations where you would have to pick it up (ie. very crowded areas, up and down square curbs).
If you have the balance to ride one of those iSlide things, you might as well ride a longboard or mini instead.
I really don't see what type of consumer they'd be catering to on this one...
