Most people probably leave their macs running all the time anyway, making the button infrequently used.
Used to be back in the day power and reset were very much needed, to the point that I wished they were on my keyboard.
Now, almost never need them.
I almost never use it either, but I don't see how that comparison is relevant. That's a portable computer with a battery. I always turn off my desktop computer at the end of the day.
The last time I turned on my M1 Mini was when we moved. The previous time was when my desktop UPS kicked the bucket and I had to swap a new one.
It sleeps in a low-power mode and is 100% silent, why would I bother turning it off and waiting for everything to boot up every morning?
Because I don't have an UPS. If the power goes down, the desktop computer crashes and there could be file corruption.
