Kind of like mini-USB, which was briefly popular but quickly supplanted by micro-USB. I think my only surviving mini-USB device is a bike light battery.
My Happy Hacking Keyboard—which I bought comparatively recently, maybe 2017 or so—uses a mini-USB connector! Really solid piece of hardware, and I guess they just didn't see a need to update a design that worked.
I much prefer mini usb over microusb, what a crap connector that one is. You look at it wrong you've bent the male end and hollowed out the connector.
I have a 3tb external drive that used mini... I'd need to find, or buy a new cable if/when I ever try to use it again.
Mini usb is actually more physically robust than the thinner microusb. I've never had a mini bend, but many micros. And it was much easier to get it right on first insert.
