The initial implication, "Dell's webcam implementation sucks. Apple's is better because of the resolution and position, which allows facial recognition".
Apple's resolution was equally as bad as Dell's until eight days ago.
Dell's position allows facial recognition without cutting into the screen.
So my point is that contrary to several comments implying how "obvious" it is that Apple's webcam implementation is superior, it's not necessarily obvious, nor superior.
And Dell supports Windows Hello 3D face recognition without a notch.
It's not quite as unbalanced as you imply.
