Regarding the power supply I suspect that right now we are in transition just like when Apple was late on updating updating the design of the late intel notebooks. It seems like they know M1 was on the way and focused their efforts on that knowing that Intel was going away. If Intel was not going away my guess is that they would have resolved the later thermal/design issues of the laptops sooner. Same goes for this power supply. We are probably moving towards even lower power consumer chips and while the current power supply is pretty small, just imagine a more power efficient base line M2/M3 chip + GaN based power supply. Maybe they could power the machine with a tiny cube shaped PSU or just have a usb-c connector coming out of the back.
