Say you are a mac user and want a portable Linux environment to play with that has GPIO? (That you can use on a plane)

You want to run a secure off line personal Certificate Authority (a Pi Zero would probably be enough and can work in the same way)

It can also be any other type of USB device, e.g. a HID device (keyboard/mouse/joystick) you can dream up loads of interesting things to do with this

I use a 3A+ for this. Works great, uses a lot less power, and is smaller.

The power draw is better with the new bootloader (lets the whole USB stack drop into low power mode)

Also this is USB-C native for all the mac book folk out there that hate to carry all those adapters
