Shamrock, I read that somewhere but could not find the information on it again.
Andyz, I think this is a similar article you referenced but this one is from apple.
Using iPhone, iPad, or iPod with multiple computers
It basically states that you may change your sync mode to "Manually manage music and videos. It is a check box near the bottom of the Summary tab in iTunes. Using this method you may use your iPod, iPad, iPhone, as a disk to transfer music from machine to machine.
Since I was a all Mac users, I had to reformat my iPod to be used on Windows (meaning erase everything and then reload everything.) I was then able to use the method in the apple support page to make a copy of my music on my Win7 Netbook.
