Most of today's 7-inch tablets, including the Kindle Fire, Nook Color, Nook Tablet, and Kobo Vox, don't have a camera. But the Nexus 7 has a 1.2-megapixel, front-facing camera designed primarily for face-to-face chats via Google+, Skype, and other videoconferencing apps. You want a rear-facing camera too? Sorry, the Nexus 7 doesn't have one. You might try the Samsung Galaxy Tab 2 7.0 instead. It has dual cameras: a 3-megapixel rear shooter and a front-facing VGA camera for video calls.
