Being that the only iPod I own is a shuffle, can someone else answer if this new "folder" thing gets synced to an iPod? While the folders can't hold tunes, they can hold playlists and folders, allowing a somewhat odd hierarchy.

Smart Playlists now know about podcasts, so I can finally have auto podcast syncing to my Shuffle.

The new look, I think was more of a way to show not much has really actually been added to justify the 5 version, but they ran out of 4.x versions.
