I've been reading that site on and off for a week and it looks great 
at first glance.  I was made aware of that when someone posted the 
link on the BasicStamps list.

I went to check out the cards and they are tiny.  I guess 
minatureization is great for cameras, but something with a little 
more mass seems to add 'value'  in my case, reducing the fear of 
losing a $30.00 chip from my pocket.

There is a PIC site that also uses the MMC card.
http://www.compsys1.com/workbench/On_top_of_the_Bench/MMC_Project/mmc_
project.html

Haveing the memory removeable and with a USB connection is derirable.

And, I think there is a USB reader for the MMC chips....  need to 
check into that a little more as well.

I think the REAL bottom line for me will be ease of makeing it work.  
And it seems those USB memory sticks are out of the question for me.
