Q: I own a 20 GB iPod and recently bought my wife a color-screened iPod. Can I use her color iPod with the computer where the 20 GB iPod is linked and share the existing music library?
A:Yes, you can.
When you connect the new iPod, you’ll go through the steps of the iPod assistant, where you name the iPod and choose how you want to sync music to it. In your case, you’ll simply have two iPods synced to the same computer, each syncing the same music.
