A notch looks really bad as far as I am concerned, but the reasons for having it make more sense on a laptop than they do on a phone.
Personally, I think differently about that last bit. IMO, the biggest argument for a notch on the phone is that a fundamental aspect of that whole product is
size... to fit in a pocket. Laptops are NOT overly dependent on squeezing into such tiny spaces. There's room for the camera to be fully in a bezel... if not THESE bezels, then bezels made modestly "thicker."
How thick? Apple just sold me an iPad Mini 6 with a 1080p FaceTime camera in a notch-less bezel... possibly the SAME 1080p FaceTime camera in these new MBpros? I haven't yet seen the new MBp in person so I don't know the relative size of those bezels... but the MBp I do have has relatively fat bezels vs. the ones in this Mini 6. So these look VERY thin in that comparison.
So maybe these new MBp cut even more bezel thinner than the dimensions of the camera... thus the need for some kind of notch or hole punch solution? OR, hypothetical option B, make the overall case of the laptop only a little bit bigger to fit in the thin iPad Mini-sized bezels around the screen. Then 1080p FaceTime camera is fully in notch-less bezels... this "extra screen" we're slinging around is fully realized too, much as if the notch could slide up into the bezel revealing that "extra" obscured by it too... AND we get the FaceTime camera upgrade.
How much bigger would that case have to be? Again, I don't know the size of the new bezels but if they are- say- about HALF of what appears to be about 10mm bezels in this Mini, add 5mm to the top and bottom of the the laptop case to put these bezels in it. 10mm more would still fit every laptop bag and I doubt anyone could notice the difference if Apple opted to roll that version out.
What does seem obvious though is that the general sentiment seems to be crowning these MBpros as laptop perfection "except for that d*mn notch." So whether one "loves the notch" or rationalizes it by some logical/illogical spin, had Apple gone option B, every benefit slung by the pro-notch crowd would still be there... and the one thing not liked by the notch-haters would not be there.
Since Apple just fit a 1080p FaceTime camera in thin Mini 6 bezels, they certainly COULD have done that here too. I don't look at the bezels in this Mini 6 and see "fat", "huge", etc bezels. If it turns out the bezels in these new MBpros ARE about the same size as the Mini 6, I won't be able to make any sense of what inspired the notch: maybe the other stuff in a future FACE ID MBpro needs more vertical space than the Facetime camera, so Apple went ahead and created the (empty) space (now) for something to come in next-gen models next year (or two)?
