I am thinking about getting the 20GB Refurbished Ipod from apple.com for $300. This is a second generation ipod right? Does it have an audio out port, so i can plug it into a car sterio, etc.. And on the this ipod can you make playlists while listening to music (listen to a song, and then click to add it to your playlist), or do you have to make playlists on the computer and put them on the ipod?
