> Considering the relative rarity of SD cards compared to microSD, other than photo- and videographers who aren't really a core demographic, welded as they often are into the Mac ecosystem, I can see why it's not the biggest priority and it certainly doesn't smell of dishonesty. I mean, why would they even be up to shenanigans over SD cards of all things?

I do wonder how true it is that the "put microSD cards in your computer" market is smaller than the "put SD cards in your computer" market.

If I think of the devices that I have microSD cards in (Nintendo Switch, Steam Deck, Windows tablet, phones), they're all devices where the microSD card just lives in the device and only gets removed when I'm upgrading the device. Or I guess there was the time I installed CFW on my 2DS XL.

On the other hand, I take the SD card in and out of my camera much more often, despite it getting less use than the aforementioned microSD using devices.

Not to mention most microSD cards are sold with a microSD -> SD adapter, so to me it feels like if you're going to do only one adapter, you'd do SD.

I think the SD module won't be able to have the card flush. SD cards are 32mm long, and you need some PCB space for the socket cage and the USB-C on the other side. The retrofit PCB outline they provide is only 26.9mm from front edge to back edge, so an SD card will stick out a little bit.

So perhaps they decided to first go for the one that lets users have the card flush for use like an expansion bay as well as for data transfer to/from devices.

Just one single anecdotal data point, but: I'm not sure the last time I've even seen a full-size SD card, let alone used one. I don't use microSD a ton, but enough that I'm glad I have the expansion card for it.

I do think my DSLR takes a full-size SD card, but I (somewhat sadly) haven't touched it in years.

In the 3D printer market it has been pretty common to be moving micro SD cards around for that. A few printers use USB A, and there are mods to swap to full size SD cards/internet connectivity for getting your files to your printer, but micro SD was the standard until just recently.
