iPod question



Insane in the Brain
Hi All,

I setup a friend's iPod recently and hooked it up to my PC to put songs on it.

My question is, what is going to happen when she hooks it up to her own PC? I generally turn off the automatic syncing because it's annoying and I'd rather manage the music manually.

Once she plugs it in and iTunes recognizes it, if she clicks "manage music manually" right away before it starts syncing, will it keep the music she already has on there?

Is it easy to use multiple iPods on one PC, or multiple PCsfor one iPod?

Any feedback would be great.
