One of the most useful things my husband has he says (besides me that is) is the external hard drive he bought. He collects music to play on his ipod or his computer when we are home. We also take a lot of pictures. Having a portable place to store these files is very convenient as a back up and a way to carry them from place to place. Now if we know we are going to visit someone we may want to share pictures or music with we can just grab the hard drive a cable and go.
