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).
