If I understand the articles written on Wikipedia (and if they are correct), it seems to me that non-SD cards go by the name MMC (MulitMediaCard), they are the same size as SD cards, and can be read by most devices designed to read SD cards. The SD cards are called that (Secure Digital) because they provide SDMI-compliant (Secure Digital Music Initiative), high-level of copyright protection. The "Secure" in Secure Digital comes from the card's origin. To create the SD card, Toshiba added encryption hardware to the already-existent MMC, to calm music industry concerns that MMCs would allow for easy piracy of music. In theory, the encryption would allow some enforcement of Digital rights management schemes on digital music, but the capability is rarely used. (A lot of what I just wrote is cut and pasted from Wikipedia.) When I bought my SD cards for my Treo, I didn't know it that was what the "secure" in SD meant, and would have at least tried the plain old MMC cards to see if they work the same.
