I'd love to keep the form factor of the Nano 3G, it's just the nicest one of them all. It's a baby brother to the bigger Classic.

What would be great is to change to a custom PCB with USB-C and an OLED display. Not sure how Nano 3G case can be made to work with USB-C though.

For software I was quite happy with Rockbox on my bigger Classic.
