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.
Why can't the most valuable company in the world just engineer a solution? Dell was able to fit infrared facial unlock inside that tiny bezel too, so I don't really buy the "it's for faceID" argument (especially since they didn't include the hardware this time). It's a ridiculous decision by a company that deserves to be ridiculed for cutting corners on a professional device.
