The video is pretty straightforward showing the zombie hand holding the Nexus 7 while an actual human hand navigates into the Google+ app, and starts up a Hangout with one of his circles. It's definitely a good way to use the tablet. There is a reason why Google was sure to include a front-facing camera on the device, but decided against adding a rear-facing camera.
How many out there use Google+? Do you often join Hangouts? If so, would you join or start a Hangout on your tablet?
