Paul O'Brien from MoDaCo created an 'app' that adds the shortcut to the default camera app back into the Nexus 7. For some reason, even though Google included the entire camera application in the build, they removed the launcher icon. You can find it on the Play store at https://play.google.com/store/apps/details?id=com.modaco.cam...

I'm guessing a lot of the camera apps check for a rear camera and block themselves if it's not present. Since Google seems set to sell a bunch of these Nexus Tablets I'd imagine those apps will all get updated to work with its front camera.

well i think google's exclusion of their native camera app is telling. this device is not intended to be used as a camera. you most likely have a much better one in your pocket at any given time: your mobile phone.
