How can i use my iPod on two different computers?

Question

I recently bought a new laptop and i plugged in my ipod shuffle but i cant add any new music to it because it was originally set up on my old laptop. Unlike other ipods, when i plug it back into the old laptop, there is no box to check like "Manually manage" or whatver. Is there any way for me to set up my ipod on my new laptop without restoring it to its original settings and losing all the other music?

Answer 1

If there is no Manually manage music setting, it must be a 1st or 2nd shuffle, not a 3rd or (current) 4th gen shuffle.  The older shuffles act like simple playlists.  You can only associate that shuffle with ONE iTunes library at a time (just as a regular playlist in iTunes belongs only to one iTunes library).
So, the answer is no.  However, you can put the songs on the shuffle currently into the new computer's iTunes library, then sync the shuffle to that library.
For songs that you purchased from the iTunes Store, you can re-download them on the iTunes Store Purchased screen.  You can also use iTunes to transfer songs you purchased from iPod to computer. 
For other songs, you cannot use iTunes to transfer song files from iPod to computer.  But there are third-party methods and utilities that can transfer from iPod to computer.  If you do a Google search on something like "ipod transfer," you should get some links.
Once the song files are on your new computer, add them to the iTunes library by dragging the them (or the folder containing the song files) to the iTunes window.  After confirming everything is there, you can sync the shuffle to the new computer's iTunes library.
