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.
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.
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.
