Asus Explains Why The Nexus 7 Has No Rear Camera

"To make this device accessible to the widest possible market, price is very important. ASUS believes that for this device a good rear camera is important. Adding a high quality rear facing camera will increase the price point and many users would not have a use for it. Adding a lower quality rear facing camera would compromise on the  overall user experience so the decision was made not to include a front facing camera therefore keeping the price down and user experience extremely high.” – ASUS
