Interesting that the only time I need to reboot my M1 mini using the power button is after a power grid failure (so, only a few times a year). All other reboots for system updates, etc., are done via the OS. From my perspective, the unorthodox placement of the power button exemplifies how user-friendly and stable the current Apple hardware/software platform is. Walled garden benefit, for sure, but I'll take it. For now.
