Designing Raspberry Pi 400
My biggest disappointment is that they did not put enough effort into designing a PCB except to "unfold" the existing RPI4 one. The biggest drawback is the micro-HDMI ports instead of the full size one. Even with space constrains a lot of people would prefer one full-size HDMI port instead of 2 micro. My other wishes are compute module, M2 socket and RTC on the board, but obliously driving cost down prevented this.
