I never use the back camera on the iPad :-) I would like the face unlock to work both in portrait and landscape, but otherwise the camera in the back might as well not exist.
Pretty much the only time I use the camera is if I'm using my iPad to take notes at a conference and I want to insert a picture of a slide. And even then it's awkward. Usually I just take pics of slides on my phone and insert them into a doc later if I'm energetic enough.
