I'm definitely interested in the Nano 3 but the power supply being USB C seems.... odd to me.

I'll be following this post with interest
The reason for USB-C or more precisely, USB-C PD, is simple: It is becoming the standard for DC power delivery to small(ish) devices. ref
https://arstechnica.com/gadgets/2021/05/new-usb-c-type-2-1-standard-offers-up-to-240-w-power-delivery/With PD's output voltage being negotiated between devices (5, 9, 12, 15, >20 & now 48v) it is a huge step to a truly 'universal' PSU.
It also means increased complexity and therefore increased likelihood of failure, which increases the likelihood that you'll have to replace it sooner and/or more often, which spells profit.
