apple wanna 'show it off'
The only reason they might not is that they want to keep everything across the entire line, and the highest end Mac Studio probably needs more power than USB can offer.
The internal power supplies in Mac minis have been extremely reliable and the fewer cables the better, in my opinion.
That gives a lot more options IMHO on how to handle power for this machine, including portability, even if it's supposed to be a desktop machine.
I thought the same for the minisforum machines which would be competitive to this, they have a 19V input that really should be USB-C at this point.
The thing is, M chips run so efficiently that even with the power loss from conversion, it’s still pulling less power than a lot of PCs.
But yeah it running on a sleek dc battery would be a lot cooler

Also just connecting the mini pc to a monitor with PD and not using any extra power brick at all seems like the much more relevant comparison.
