I thought the main advantage was that reading from a flash cards  
takes less battery in a laptop/ipod/phone/....  They aren't  
particularly fast compared to a hard drive and still insanely slow  
compared to real memory.

Also: Consumer flash cards have a very limited number of write cycles  
before they burn out.  "Industrial" cards are much better, but at  
least in low quantities they are quite expensive (relatively).
