Having ports on both sides of the machine. I use a usb-c display and need to flip the laptop upside down when docking. Otherwise my cables would get a bit messy or I’d have to rearrange my desk to avoid direct sunlight falling on the main screen.

Tbh, I have barely used the desk since I bought the machine, so we’ll see how much of an annoyance this will become in autumn:)

I have a M1 Pro 16 as a work machine and a personal M1 Air. The screen on the 16" is much better (higher refresh and brighter)
