I'm taking a trip soon and would like to avoid bringing my laptop. I'm hoping to bring enough camera cards for the entire trip. When you download pix to the iPad with the connection kit, do they go over at full size? And how to transfer them back? I usually just email them to myself if I want to see them, knowing I can put the card in the computer at any time. I'm worried that if for some reason I need to empty a card, I'll lose some quality in the pix. I remember thinking this would be the ultimate tool while away but I didn't have an iPad last time I went away. Thanks!
