Per the users guide, a playlist you make on the iPod will sync back to your iTunes library on your computer. One the playlist is in your iTunes library just sync the playlist to your other iDevices.
From Users Guide:
Create a playlist:
1 Tap Playlists (tap More first, if Playlists isn’t visible), then tap “Add Playlist…”
2 Type a name for your playlist, then tap Save.
3 Browse for songs using the buttons at the bottom of the screen. Tap any song or video
to add it to the playlist. Tap Add All Songs at the top of any list of songs to add all the
songs in the list.
4 When you finish, tap Done.
When you make a playlist and then sync iPod touch to your computer, the playlist is
synced to your iTunes library.
Thank you for the reply. I appreciate it, but unfortunately, I didn't create the playlist in my itunes. I created it right to my iPad. Instead of meticulously going through my songs again to make the exact same playlist, I was wondering if there was a way to add the playlist from my iPad (or iPod) to another device. Any suggestions?
Read lllaas's post more carefully. He said, "a playlist you make on the iPod will sync back to your iTunes library on your computer. One the playlist is in your iTunes library just sync the playlist to your other iDevices."
The necessary intermediate step is to first get the playlist to your iTunes library. From there it can be placed on your other devices.
Thanks JimHdk. After reading it more carefully, I am still having the same problem. I can't get the playlist back to my iTunes from my device, to then sync to other devices. How do I do that? When I click on the iPad, and click "sync music", it wants to erase everything on the iPad. I don't want to do that. Am I missing something?
