i have 2 computers and i sync my new ipod with one of them, so i want to know if i can upload songs from either one of the computers with no problems. i've heard that you need to erase all the contents in order to upload songs from another computer but i think apple is better than that. I ask because my brother who owns an ipod video told me he was able to tranfers songs using another computer without erasing the contents his ipod had. Also, what if i want to hear music on my work computer using the computer spakers instead of the ipod using songs that are stored on the ipod? I hope someone is able to help me.
