An actual hoverboard→

Ars Technica:

ArcaBoard appears to be the closest we’ll get to an actual hoverboard in 2015. Designed by the US-based Arca Space Corporation, the mattress-shaped vehicle packs 272 horsepower and is propelled by 36 ducted fans spinning at 45,000rpm. Buying one will set you back about £13,500 ($19,900).

And it’s not stuck to magnetic bits:

While looking a bit awkward and unwieldy even in the promo videos, ArcaBoard is said to be able to hover over any terrain, including water and uneven surfaces like rocks or rail tracks.

Now we just need to get really good at wireless power, and we’ll be able to use these sorts of things for more than twenty minutes at a time.
