If the idea of charging via cable is of huge inconvenience for you and sounds messy, Hitachi Maxell has announced what they're calling the "Air Voltage", which combines a wireless charging pad together with a jacket that has been designed to allow the iPad 2 to be charged wirelessly. While technically there is still a cable involved, which connects the wireless charging pad (dubbed the Energy Stand) to a power source, the iPad 2 itself is not connected by any cable at all, which means there shouldn't be an occasion where tripping over the cable will cause your iPad 2 to come crashing down with it.
