Yeah, it's looked pretty but until someone invents a Mr Fusion, it ain't ever going to happen. Using thrust to keep you in their is very, very costly without decent sized wings. Wings which can't be strong enough and foldable/stowable to offer much lift unless they are small which means very high horizontal speeds to be useful. Compare a jet fighter with a glider.
