It often amazes me how much photographers seem to hate switching CF cards! They are so easy to change that I don't really care what size (1 GIG and above) that I am using. I have a selection of two and four GIG cards which are backed up by several one GIG cards. I even have a few older 512 MG cards which I will use when I want only a shot of two. BTW, I shoot raw with 30D and 40D cameras. Perhaps if I shot with full-frame equipment; I might want 4 GIG and over cards.
