One commenter on the Wired article already said what I was going to write here, so I'll just quote this: "The biggest problem is that everyone INCLUDING this article intentionally ignore one aspect and will not speak it. The hoverboard will only work on it's Copper plate surface or the Aluminum surface. It will not work on your driveway, on a sidewalk, etc.. you need a thickly skinned surface of copper or aluminum for it to work at all. So unless you have several thousand dollars worth of 1/4" thick copper or aluminum sheeting around, this "hoverboard" will not work. It's NOT a real hoverboard. It's a maglev board that will only work on a very specific surface that happens to be made of some of the most expensive metals around. Copper and Aluminum right now has a very high cost."
