Where’s my flying hoverboard? (Back to the Future)

From The Daily Beast:

Greg and Jill Henderson, founders of Hendo, have developed a real hoverboard. Yes, the flying skateboard that millions of moviegoers have wished were real since Back to the Future Part II premiered back in 1989 may become the must-have Christmas gift for 2015. Using “hover engines” that create frictionless magnetic fields, the hoverboard only appears to hover an inch or two off a metallic floor. It’s not exactly ready for, or usable on, concrete but everything has to start somewhere.

There is more here.  It needs something like a copper sheet below it.  There are different accounts here, with varying degrees of enthusiasm or lack thereof, I found this one useful.  Still, this is more progress than we were seeing a year ago.
