Well I have to say nano hands down. I only have about 5/6gbs of music on my computer and generally when I add a few tracks I delete a few as well. The nano can play videos too, but neither the video nor the nano have screens large enough for me to enjoyably watch a clip longer than a few minutes. I actually believe the video should just be eliminated from the line all together. The Touch can do everything the ipod video can, but with a larger screen, touch interface, and the power/capabilities of a mobile computer. It's only a matter of time until the Touch drops in price and the Video is eliminated all together.
