what happened to mini SD cards anyway, and why did they disappear when both micro and regular stuck around?
@Felthry Probably because those two are the min size and max capacity variants. Mini ended up being eaten by micro once micro hit a certain size, because either micro is big enough or you need huuuge storage for video or something.
@Felthry Going to guess that micro to mini adapters ate a chunk too before they died, kind of how micro to full SD are now. (Not claiming SD will die. That capacity bump still seems useful enough.)
It feels like they ought to be a good compromise between fitting larger flash chips on them and physical size of the card, but I guess they failed before that became a thing worth caring about
