apple, ipod

I tried out an ipod around a week ago and the ipod was great. The ipod sounded, played, and had allot of storage. When I got my ipod I had to do some installing on my computer, which my computer took a long time to do install it because the pc is slow and the computer always has been. The ipod can hold a few hundred songs, although I did not have that many songs, but I did have a couple hundred songs to listen to. I had all my favorite songs first, then I added the ones I listen to somtimes, and finaly I added the onest I do not listen to as much. When I added all my songs I wanted I listened to my ipod and after a whilei kept charing the battery but the battery kept on lasting shorter and shorter of time between the time I charged it and when the ipod battery died so I stopped using it.
