I have two questions. 1. Is my ipod suppose to reboot, (apple logo comes on), every time I plug/unplug the cable to sync? It reboots and I have to wait for it to come back on. I do not remember this from an earlier ipod I owned a while back. 2. I have an imac and an ibook. I want to be able to sync the ipod with both. Is this possible? When I plug it into the ibook, (after syncing with my imac), it does not give me an option to combine/sync with what is on the ipod's hard drive. It asks if I want to replace the library with my ibooks itunes library. I have downloaded some music from itunes music store and I have the songs on my imac. However, I want to sync the ipod with my ibook so both of my music libraries will be up to date.
