What is up with wireless charging?

I thought of this in 1992, Sony made a waterproof phone that had no metal connections to charge in I believe 93 or 95. I don't think its that big of a deal, I am wondering how it will work in the car.

 

The real reason why it is not on iPhones is because of the all metal enclosure. It is very difficult to transmit power through metal alloys. That is why "almost" every android phone that has wireless charging has an either plastic or glass back. I would like to see what Apple has in store for a power transmission that allows for distance charging. So imagin a base station plugged into a wall and whenever you are within 2-4ft of the station your phone will charge. That is where wireless charging will become useful to me. Current tech still requires the the phone to be placed flat on a "mat" in order to charge. Not much different then plugging in to me.
