Does syncing take what you have on your iPod and rewrite it on your computer, or does it take what you have on your computer and put it on your iPod? This is what I never get.
I would also like to know: How can I control when I sync what to where? (So controlling, when I sync my iPod apps to the computer, or when I sync the songs I have on my computer to my iPod, or when I sync the contacts I have on my iPod to the Computer, or when I sync the calender on my computer to my iPod)
