Mh, I wonder what article author think for webcam use cases... Personally I consider them useless 99% of the time in the sense that there is no need for video. When a video is needed 480p is enough, eventual dropped frames or artifacts does not matter much. If we really need hi resolution it's beyond webcam, something about YT, TV, ... not webcams anyway. If we need to share paper docs (LIM alike) it's better scan them before.
