Google's Nexus 7 tablet may be receiving OnLive Universal Controller support soon. What the Jelly Bean-flavored device won't be getting, however, is a rear-facing camera. Now ASUS is offering an explanation for the omission -- and no, it isn't to prevent users from looking like a doofus when snapping photos in public. ASUS apparently faced two options for a rear-facing camera: go cheap or go for quality. The company says it decided against sticking a lower-end camera at the back of the device because it would compromise the user experience. Adding a high-quality rear camera, on the other hand, would increase costs too much, so that proposition was nixed as well. The good news is that apps such as Instagram are finding ways to make things work with just the Nexus 7's front-facing camera. In the meantime, here's a little ditty from Google that just might help put a smile on your face.
