Agree with Danny on card size dangers.  I need a 1GB on the D200 to get a decent number of raw but to go to a card 5, 10 or more times the capacity would likely not be my choice. Sure, it depends on equipment needs and file sizes...still, I feel more "secure" with several cards than with one huge one with everything on it.

Still, amazing the capacity of such small boxes...we will likely see more a coming.      Tom.
