Where to even start with this. What if I told you that just because you can't imagine it doesn't mean it doesn't exist? There are tons of small businesses in the physical automation space that run on hooking SBCs up to various things. Many of their components are 3d-printed, by them, until they get everything laid out just right. Source: security evaluations for the software those people write is an extremely lucrative side-hustle, and it's all word of mouth. The photography business you casually ignore is quite large (Google "wedding photographer" in your city and then realize that most photographers don't even shoot weddings). Or just realize that on the order of 200k DSLRs ship in a given month, almost all using SD as at least one of the onboard cards. Add to that the high-end mirrorless segment which is about the same size, plus all the GoPro addicts (and just to head off the inevitable "what pro uses GoPros" comment, go look at b-roll in any car review). Then round it out with the dashcam/security camera crowd that either doesn't trust wifi or is required to have on-device recording for regulatory reasons. There are also lots of scientific instruments which use SD cards for data logging in remote locations, especially since they're cheap so you can buy 2-3 from different manufacturers and duplicate the writes without appreciably increasing cost. Ditto other kinds of data loggers like IoT stuff that actually uses an air gap.
