The Nexus 7 features a front-facing-camera that was intended by Google to be used for video chatting on Google+ hangouts and other services. The MoDaCo development team has released an application for Nexus 7 users that allows them to launch the camera from their homescreen, and take pictures. Previously, Nexus 7 owners were unable to do this due to a lack of a camera application. If you own a Nexus 7 from I/O, or have pre-ordered one, hit this link to get the app!
