Hey, this is a great post! My wife and I enjoy some good mood music (if you know what I mean) for our cabin, so I bring my iPod. An extention cord allows you to run extra things in the room (rechharging batteries) and you don't have to lean over to get to a difficult spot. I also like to bring Walkie Talkies for when the wife and I want to go in different directions whether we're on or off the ship. Comes in very handy and seems like a lot of other people bring them too!
