When I plug my iPod Nano into my wife's computer and boot up iTunes for the purpose of syncing onto my unit a seven CD talking book that she had loaded into her iTunes library, taking about an hour, I could not sync that one folder but was given only the choice to erase everything on my iPod and replace it with her entire library. I can understand the problem with sharing material rather than buying it from iTunes, but this material was purchased by us independently elsewhere. To avoid this problem can I save the file to another location and then import it into my iPod? This restriction is crazy. There must be a workaround.
