iPods are either formatted for Apple or PC, they cannot be both. If you initially set it up to sync to an apple computer it will not be able to sync to PC. In order to get it to sync to PC you have to reformat the iPod and sync to PC, so yes you would lose all the songs on it. AFAIK anyway, there are programs that allow you to save songs from your iPod to your computer, but if it's apple you can't connect to PC and same goes the other way. You can have up to 5 computers authorized for your library, and you can have 4 or 5 iPods on 1 computer.
