Oh...How disappointing. The web site I ordered from (DVDBoxOffice) 
clearly used the MB unit with a capital B, so I just assumed they meant 
bytes (that's the common thing to do for storage :). And the label on 
the card also sports a clear MB unit. But you're probably right that 
they mean bits...

Yeah, after checking, I find that it is advertised to have 1019 blocks 
(1024, including 5 "filesystem" blocks). With each block 8KB large, 
that's 8MB.

Well, then at least its _some_ persistent storage for the system...I'm 
now even happier that I didn't buy the Nintendo 4 Mb card (59/64 
blocks) that was even more expensive than the 1024 one...Half a meg, 
that isn't much to cheer for.

Sounds great.
