I'd not get into the device support part, because I don't own a Zune so I don't know how it syncs with the software so I'll just discuss the interface for music library. I have to say that the interface is beautiful with the Metro UI, elements that fade in/out, the auto-collage of album art, the responsiveness. Just as a music manager, Zune is WAY better then iTunes. It just looks hip, cool, artistic. Wasn't Apple supposed to be that?
