Additional components or functionality can be provided for a computing device by coupling the device with one or more device skins. Each device skin can include one or more components that can be utilized by the computing device, such that a user of the computing device can obtain desired functionality by selecting an appropriate skin. The components of the skin can be powered by the computing device, such as through wired or wireless power coupling. The computing device can determine an appropriate control scheme for the skin when the skin is coupled with the device, enabling a user to utilize the various components of the skin as if those components were part of the computing device.
