One thing that has held the SD card back from wider acceptance is the
slow rate of divulging exactly how the interface operates. Although
it's pretty well-known now, in earlier days you had to go scouring
the net to find much detail.
If you stick with the SPI interface, you can also handle MMC cards as
well, although they're rapidly disappearing.
And there's micro-SD, which almost feels *too* small...

Why not the SD
card? Cheaper, smaller and easy to interface! :)
My gut feeling is that compact flash will live a little longer in
terms of being able to get interface hardware a decade into the
future. But I could be wrong and SD might have more legs (certainly
fewer contacts). And as you point out the serial interface to a SD
card is very straightforward so I think you have a good point!
