Logitech's 'PowerShell' iOS 7 Game Controller Now Available
Logitech's controller also includes a 1500 mAh battery which will charge an iOS device whiile it is plugged into the controller, and can also be charged simultaneously with a device through the controller's micro-USB port.
Rumors of Logitech's controller originally surfaced with a photo of an early prototype back in June, with Logitech teasing the controller's existence in September. The final design of the controller is also consistent with leaked images of the device released in October.

The Logitech PowerShell Controller is available today for $99.99 from Bestbuy.com and the Apple Online Store, with an expanded international release set for December.
