I've been adding miniSD cards to ARM-based media players recently:

There's a problem with SD cards in general in that they're heavily
licensed, and in theory you can't get specs, or use them, or buy
sockets for them, without paying $$$$ in SD-assoc membership fees.
(people get around this by using them in MMC/SPI mode, but there's
some question as to whether SD cards in general, and especially the
newer packages, always support that.)  (Sparkfun apparently sells
microSD sockets.  And someone pointed out that if you're careful you
can use the "adaptors" that usually come with the microSD cards as
sockets...)

MicroSD and miniSD are still somewhat more expensive than full-sized
SD, and IMHO, the "sweet point" for cheap microSD cards is almost
too large for typical embedded use.  Gimme those $4 32M (full sized)
MMC cards instead...
