    Low power draw but ridiculous power supply requirements of 5V5A (depending on the model) with a USB-C connector which isnt a thing outside of this specific application meaning they’re going to be expensive and hard to source.

    That’s only for the Pi 5 (the highest end unit), and I’ll agree that at that level its hard to justify a Pi over a larger computer. Even for the Pi 5 its not that hard to find those Power Supplies. Most laptops today use power supplies that meet or exceed those specs. You’re right that those are more expensive than Pi 4 and below Power Supplies.

    They should have just done a barrel plug or put an effing voltage regulator on board like Arduinos.

    Again, no defense of Pi 5 from me. However, for everything below Pi 5, HARD PASS on a voltage regulator. I don’t want that heat in the tiny Pi case. At the lower power requirements of Pi4 and below USB power is fine.

      Yeah a voltage regulator would be a bad idea, however a well designed DC-DC buck converter can be in the 95%+ efficiency range and produce very little heat.
