I'm kinda not understanding the benefit here? If I have already have all my music on my devices via sync then what does this do for me? Can I delete the music on the device to free up space?
no not true on the power part.. I reinstalled itunes and rebooted the pc, re-launched itunes and bam my iphone and ipad showed up hit sync on each one and it worked.. now I need to see what happens when I close itunes and restart
