Curious- what's shipping with micro usb? I had to find a micro usb cord to charge an older device a few weeks ago and probably have 1 or 2 cords compared with 15 or so USB C cords (and I've never bought a USB C cord outright- those are all from products that shipped with C).

As for mini usb, the only thing I own that uses it is my TI-84+ calculator.
