Considering even budget Android phones have 4K cameras. The Macbook Pro should have a 4K webcam. I can't imagine they cost much if they are being put in sub $300 phones.
More ports would be good. Then again it has four all purpose video ports. I'm not sure HDMI is necessary. As that limits you to one standard. So, you'd still need to carry adapters (dongles) for connecting to other video devices anyway. For example a lot of offices still have VGA projectors. With Thunderbolt you can just carry one small dock which connects to a wide array of video devices. Plus standard USB, Ethernet and SD.
Even a micro SD port would be great. So, one can expand storage internally.
