Adaptive Memory Card

[trickykitty]

I think this is an excellent idea, but for some reason it doesn't appear on the surface to be very practical. Wouldn't it always be excessively sticking out of a device that would require you to use one of the adapters, like for instance a camera that required a ProDuo card (like my sister's camera)?

Also, I have no idea if the price of the 1-2-or-4 GB adaptable cards would be worth it.
