I'd wish Apple would start the "trend" to remove rear facing camera's on tablets. Perhaps its acceptable on the iPad Mini, but with iPad Air and any larger iPad Apple has planned, Apple just needs to say now.
Seriously a tablet is the worst form of camera short of those big wooden boxes with the black hood you have to put over your head and the large fire bomb used as a flash.
Instead this is what accessories are for, like Sony's hand-held wireless camera lenses. At least then you can sit the tablet on your lap and hold a much smaller and less obtrusive lens to record video or take pictures.
There is nothing worse then someone missing out on real life because they have to record everything with a tablet screen inches in front of their face, but it is worse when you are the person that is forced to sit or stand behind someone that is blocking your view with THEIR tablet. It will be even worse when all those douchey people start using a large iPad Pro as their primary video camera.
