That's right. My recollection is the original x86 PC could boot MS-DOS from a floppy, after which it was possible to remove the floppy. I think the PC sometimes asked for the floppy back, for example, when it needed to reload COMMAND.COM or similar.One could do the same with an x86 PC, so the existence of OSes running entirely in RAM (once booted) doesn't change either the initial question, nor the answer I gave. In general, one does not expect a system to run if you remove the mass storage device after it has booted. This is true of both Pis and PCs. I submit that the question is naive.It is possible to create an operating system that boots from the SD card and then runs entirely from RAM. For example, this is what Tiny Core Linux does.
That is the equivalent of asking if you can remove the HDD/SSD from a PC after you boot from it.
Getting back to the Pi, in my opinion the card slot is not well suited for repeated insertion and removal of SD cards. Though I don't know what the rating is--maybe 10000--even so, Fido would likely break it after less than 1000 insertion and removal cycles. I wonder how they hold up in school settings where each student uses an individual SD card each day for their work.
