Can i ask why you don't want to use iTunes?
the reason why I dont want to use iTunes is because I can find a way of putting the songs back onto my pc which are on my iphone and adding new ones which are on my pc without it deleting all the songs from my iphone (hope that makes sense).
I will continue to use it when I have enough money for a MBP.
iTunes is fine unless you want to sync it with more than one library, then it's pap. I use Sharepod to copy music from iPhone to my PC so I can sync it.
