For ipod nanos, you should be able to select which playlists you want sync'ed. The entire music library doesn't fit on these devices. If you manage this manually, it doesn't copy the playlists, only the songs. And it should warn you that you don't have enough room on the device for the entire library and have that option be greyed out.

The ipod manage window should have
Music Library
     Sync Music Library
x Sync Only these Playlists
       x playlist 1
              playlist 2
       x playlist 3

Songbird has this. This is the only reason I'm using songbird still.
