"A number of consumer portable device companies manufacture their products
with slot(s) supporting both MMC and SD formats. Beside price, the biggest
advantage of the MultiMediaCard standard -it was developed for all the
leading open systems platforms. This technology is an open standard
available to any company who wants to improve upon it or develop products
for it. This includes Linux and all other Unix variants. Linux companies
will easily be able to develop products for MMC cards. The SD standard was
developed essentially for the Microsoft Windows platform. Sometimes, to get
at the real difference between two competing standards, one must also view
the forces driving their adoption."

Perhaps that is why SD cards outnumber MMC cards by about 90:1. Grin.
Worse, they cost more, and are less, physically, robust, being somewhat
thinner. Their advantage is lack of DRM features.
