You can use your itunes library to sync it towards as many iPods as you wish however you can only sync each iPod with one library.
yep it will sync no matter how few/many iPods you have
The same way you charge iPods. Connect them to your cord/dock and open the Zune software to sync.
Make sure the library in iTunes is the same for both iPods and then press your iPod Touch under Devices and press sync in the bottom right hand corner.
Make sure the "Manually manage music and videos" check box IS CHECKED on both of your ipods. This will take a little more work but then it will not automatically sync and will easily allow you to connect multiple ipods to one itunes - we have three ipods and one itunes at our place.
Linux software exists to sync music with most iPods. So yes.
no, sorry, just import the music into your itunes.
ipods can only sync with one computer at a time.
in ipods and phones etc. syncing is basicly dowloading or deleting files from the phone/ipod so it is the same as the computer depending on your choice
No, it will sync every copy to your iPod exactly the same as in iTunes Library
Yes. You cannot have two iPods syncing to the same library, but if you get a new device, you can override the old settings with the new ones. The new iPod will sync with your existing library.
In iTunes, syncing is when you make the contents of your iPod the same as what's currently in your iTunes library.
