I recently got an iPod Mini from a free site since my older 20GB one is dying out. However I still do use it for some occasions, so here is my problem:

I have about 7 GB of music. I want all of it on the 20GB but only some of it on the Mini. Is there a way to create two seperate iTunes for each iPod? So when I go to update one of them, it recognizes it?

i dont use itunes, i use winamp with the ipod plugin, but anyway you would probbably have to disable auto update and then create two seperate playlists.
