It's not wrong per se, the OS is installed to the NAND which is the internal memory. Regardless, a noob is going to understand it AS the OS, and nothing more. If they were more curious or tech savvy, they may be interested further. To help a noob you have to think like one, half of them don't even know what the root of their SD card is, I don't expect them to care one way or the other. That's why I was asking. As long as they know what things DO, and what they can do with them, very little care about the how. So no, I wasn't saying give misinformation on purpose, I was saying give half-information until they understand enough to go into full detail.
