So am I correct in understanding this? It is possible to have one iPod and multiple libraries on multiple computers and be able to import music onto this single iPod. It is not possible to have one computer with multiple libraries (via fast user switching/multiple users) and manage these libraries on two iPods. (My wife and I have our own iPods and separate music libraries. I loaded all her music on her iPod and want to put some of my music from my library on her iPod.) Maybe I'm not understanding what I've read. Thanks! Merry Christmas!
