For me personally, they hit it out of the park -- except for the notch, which seems like a complete showstopper to me at first sight. Maybe it's not so bad in practice if games and full-screen videos keep that whole strip solid black? But almost all the screenshots are of fullscreen apps, so it seems Apple thinks it looks a bit ungainly too.
I can live with the notch, but honestly I would pay more for an option to remove it along with the camera.
For me, it really depends on how this camera compares with a standard Logitech C920. If it's as good or better then I'm fine with it, but if it's just a minor upgrade over the terrible pre-existing camera then I'm not sure why they would mar an otherwise fantastic product.
