WOW-Keys is about 100 bucks…
Not only does this dock and charge your iPhone, but it enables you to use your iPhone in conjunction with the keyboard and the touch service of your iPhone with the keyboard.
With the flip of a button, however, you can switch WOW-Keys over to PC mode (although it also works with Macs). Now, the phone serves the keyboard. Its touchscreen display allows it to work as a multi-touch input device for the computer – among other things, it can function as a touchscreen track pad or numeric keypad.
