With the increasing proliferation of wireless devices, be they mobile phones, PDA's, laptops, wireless keyboard, mice, portable music and/or video devices, digital cameras, camcorders, you name it, incorporating various modes of data transmission, from wifi via Bluetooth to GSM and more, any remaining wire is always a nuisance. Unfortunately, sometimes these devices need to be recharged. And that means a wire. Or does it? Interesting concept...
