I have a hard time filling up a 4 gig card on an outing....pretty selective in my shots.....and some outings I need more than one...always yave 3 - 4 GB cards in my bag as well as my trusty Epson....just for those times I really need to capture diffrent variations on a composition that I find.

I find smaller cards with the elbow room to expand keeps me thinking about my shot more....kinda a mental dicipline game if you will.
