Love the retro design, but from the looks of it, it's a heavy and fairly bulky item to drag around. I know there is no Pi 5 variant of the compute module yet, but it seems like a safe assumption one is on the way — if your goal is to design something portable, I'm not sure why you would design around the full Pi form factor and not the compute module?
