with wireless charging, you'll be able to charge your phone while you're out and about, drinking latte in a coffee shop or waiting for a flight, or at a friend's house, without having to take a charger with you. you just place your phone on a cushion or pillow or arm-rest or similar, you don't need to plug it in to anything. also around your house you'll be able to place your phone on or near a pillow or cushion or similar and it will automatically start charging without having to physically plug it in to anything. also you can charge multiple devices at the same time on the same arm-rest or pillow etc.
Nokia have partnered with Virgin Atlantic and a coffee chain to start rolling this out.
