100% with you on the IO. I've never even wanted two display output ports with any raspberry pi.

You know what I do want though? An actual damn HDMI port! HDMI cables are everywhere, wherever I am I have unlimited options to connect an HDMI device to some kind of screen. But micro HDMI? The literal only thing in my life that uses it is the Raspberry Pi 4 and 5. There have been plenty of times where I've reached for a Pi 3b instead of a 4 or 5 just because I didn't have a micro HDMI cable.

I do not understand what has gone through their head. How could anyone look at the use case for a Raspberry Pi and decide that two micro HDMI ports is a better choice than one HDMI port? I don't understand it. Like you, my experience with the Pi is that they mostly just sit there, headless, so the only reason I need display output is that it's useful during setup (because they don't have a proper serial console port).

I can't set up a Pi 4 or 5 without going hunting for that micro HDMI cable I bought specifically for that purpose and never use for anything else. I can set up a Pi 3b anywhere, at any time.
