Another thing to watch for is the quality of the card you're using.  I
worked on a multi million Dollar device a couple of years ago that stopped
working when the consumer quality cards started flaking out after a few
months of being read and written.  The commercial quality cards cost more,
but are rated for many more R/W cycles.

Steve,

A Micro-SD card and socket will fill the bill. Just don't drop the SD card,
you'll never find it!

See http://www.sparkfun.com/commerce/product_info.php?products_id=127 for
some ideas.
