Rather, what's the point of you suggesting that? The idea is to transfer images between cards on the go, not at home.
Some digicams do allow you to copy images from one card to another. I think Minolta Z1 and A1 has that, right? You can save the image to the digicam buffer then insert another card to copy it. F828 should provide this feature, especially when they have 2 slots for 2 cards.
