Camera WTF!
I don't want a camera in a iPad, neither forward nor backward facing, however, if I did, I would buy one of the little forward twisting to backward cameras that plug into the docking socket on the bottom, turn the iPad 180 degress where the picure will twist to match. Of course, they are not available YET but producing the iTab at a $499 price point is the magic in my eyes.
If you look at the accessories that Apple have announced, there is a camera adaptor to connect to any camera via USB or SD Card.
