When you do, say, extreme sports, you can attach your GoPro to your helmet, and produce an almost your-point-of-view reporting. But this is unpractical in less extreme situations.
I can imagine that various video lessons can benefit from a camera positioned right at your eyes; there are several other offers for that on the market. OTOH reporting in a social situations, like a birthday party, can benefit even more, because you don't have to carry the camera around, keep it pointed, etc, you can participate and sometimes make shots, or shoot video.
As an aside: an ideal reporting camera would have a button like "save the shots from 10 seconds ago to now", and "start video recording 10 seconds ago". This hardware likely lacks the battery capacity for such a mode, though.
