do a search on versiontracker.com and you should be able to find 2 solutions to sync a playlist to any memory card via a card reader, or by connecting the N73 to the Mac using the USB cable. however, AFAIK, you can only sync unprotected music to the card. any DRM-protected songs will not be able to play on the phone.
i don't think it's that undesired. probably just 'cause people around this part dislike Apple. if you post this question on a Mac forum, you might get better responses.
