Data point: while I see electric skateboards, longboards, and scooters in slowly but steadily increasing numbers around here, the number of hoverboards out in the wild has lived a short, hyped life and I rarely, if ever, encounter any anymore.
I'm still a bit confused - apparently "hoverboard" is being used by you and the other poster not in the 'back to the future' sense of a hoverboard?
Maybe it's living in a northern climate, or maybe we're behind the hype cycle, but I have seen 2 of those things in my life, one as a kids' toy and the other as an office toy.
This[0] is what is — quite infuriatingly — being labeled "hoverboards" by the general public. Following some marketing hype they were popular gifts around Christmas a couple of years ago, and they're mostly used as recreational devices, to be tucked away on a shelf in a garage as the hype dies down — that is if they ever survive even moderate use, since most of them are bad knockoffs. Those unicycles[1] though, are sort of growing in popularity as last-mile transportation devices, as are electric longboards and scooters.
