I purchased an Ipod touch for my son for Christmas. I'm thinking I'm doing something wrong when it comes to downloading apps, songs, video, etc onto the Ipod touch. For example this morning he purchased a song. This was the process. We went to Itunes, purchased the song and it was added to his music library on his PC. Then, in order to transer the song to the Ipod Touch, we need to sync it (or at least, that's the only way I know). This is what I don't get. I can't just sync the new song he purchased. I have to "re-sync" everything. If I don't do that, then he loses the songs he previously synced onto his Ipod Touch. I'm sure there has to be a better way and I'm just not aware of it. What if you no longer want the songs, video, apps, etc on your PC but you still want them on your Ipod Touch? Can anyone give any advice on this?
