Webcams are a waste of bezel space, might as well get a non-junk USB one. Plus you can position it for shots other than up your nose.
Give me like 8 USB-C ports and nothing else.
16:10 is OK but if we’re going for Perfect Laptop, obviously 4:3 is the correct aspect ratio.
The current Apple Bluetooth magic keyboards are fine, use that (with a non wireless interface of course).
These opinions are my own but they are also objectively correct.
