It is efficient enough...though not as efficient as plugging it into a socket. With the right contact surfaces (and geometries) and some clever signal processing you can get it so losses are negligible. Systems such as these are already used in industry when there are hazardous environments where having an electrical connection would be too dangerous (in underwater situations unfeasible).

How efficient is induction? It would be a shame if millions of phones started using this simply because it was "cool". Longer charge times, more fossil fuels burnt. Sounds like a big negative to me.
