I agree, wireless charging (at least at this point) isn't as efficient as plugging into the wall. I got a PowerMat and had to plug in several different ways just to "wirelessly charge" my phone. It made no sense at all.

Wireless charging won't take off until it's out of sight, out of mind. It will either need to be installed everywhere (in desks, at Starbucks, etc) or like Wi-Fi in that your phone will immediately pick up a charging signal (see my story on Humavox and Energous).

Given the trend toward higher efficiency an inductive power system like this is inherently very inefficient and contributes to more EMI around it.  Is it really that hard to just plug in a cable?  Now I can see such a use in an industrial setting where intrinsically safe areas exist.  Not making an hard electrical connection could be a safety advantage.
