We would like the RPi more for education, but the cost is still a factor. Due to cost, the school need to buy these, as by itself the RPi is useless; It needed a keyboard, mouse, screen, etc. Students bring their own SD card, since else they are easily misplaced (stolen). This also means boards can be used by any student. A lot of effort and cost, so we went with the microbit. The kids can easily own them, use a tablet to program them, and for the kids that are older, they can go for the rPi to expand this setup and learn more advanced stuff. By we do not use this as an entry. Kids that do robotics have a better time with them. So yes, maybe mostly used by adults. The idea of SD cards was a good one. But several flaws held it back; like the non-5v tolerant GPIO. Lost several boards due to misuse... And they ain't cheap if they need to be replaced often.
