if it was higher it couldnt be used. because you know... your 1 foot needs to kick off the ground...
an inch wouldn't make a practical difference but would look a lot cooler
plus the point of hovering isnt to LOOK like anything. its the absence of ground friction and drag that is new about it.

go buy yourself an apple product. they are sleek and cool LOOKING.
was this necessary
also apple doesn't make hoverboards, so it's irrelevant in addition to unnecessary
