I have heard that you can use an Ipod to store your pictures instead of a laptop while on vacation. I love this idea as I think it is a huge pain to take my laptop everywhere I go. However, I am Ipod illiterate! I know there are several different kinds. I would only use this to store pictures that I later transfer to my laptop upon return home. What version of the Ipod do I need? Do I need any other equipment like connectors or anything like that?
