The internal mics would be useful in a run and gun recording situation. We had some students competing in different classrooms which meant recording in one room and then immediately going to another room afterwards all day long. The rooms were too cramped for much gear, lousy acoustics, people everywhere, going and coming. You get the idea. But for purposes of just getting a recording, the internal mics could be useful. If you are doing camcorder video, I suspect the internal mics are way ahead of most camcorder mics, too. Or if you don't have any external omni mics, you could mix the internal Omni's with your external mic pair to suit to taste.
