Have any companies actually done this yet?

I'm a lover of https://notebookcheck.net/ & they have really really evolved some very good scientific tests. I can't think of the last time I saw them say a laptop camera was anything but poor.

My previous everyday-carry laptop, a Dell Venue 11 Pro, a 2-in-1 tablet- had a front-facing 8MP shooter and a 2MP selfie camera. At one point both were indeed available to me in Linux, but I think the 8MP disappeared at some point, somehow. I'd be interested to see if that was any good- the mere fact that it had two cameras is a sign that they kind of gave some kind of a crap, that maybe perhaps the (non-video-conferencing) camera might actually have been somewhat passable. Probably not!
