I got my 2 GB card today in the mail. I popped it into my camera and here's the image count.
Superfine quality + 2272x1704 res = 999 images
Superfine quality + 1600x1200 res = 1938 images
Fine quality + 2272x1704 res = 1777 images
Fine quality + 1600x1200 res = 3367(!) images
I think I'm set on pictures.
