I have one Mac with 2 users set up (my wife and I). Naturally, we almost listen to the same music but since getting an mini-ipod she has to restrict the amount of songs to fit into her unit. I have a second large drive set to hold the itunes music folder and have created both itunes music libraries for her and me. I'm wondering if this is the normal and optimal set up?
