Why would you be sitting behind the screen? If you need to film a conversation between two people with one webcam…have the webcam face their profiles
have you never been in a workshop and wanted to show someone what you’re working on? it would be awesome to just be able to fill the camera and walk over
I wouldn’t suggest that there is no use for this kind of camera. Yours is a good example. But for the cost and risk of damage, that is not something that most would want by default in a laptop.
