Sync discrepancies highlighted between Google Contacts and Address Book

Steven Frank, developer for well-reknowned software house, Panic, has put together some useful notes on his blog around synchronisation discrepancies between cloud-based contact manager, Google Contacts, and the ubiquitous Apple Address Book which comes pre-installed on Mac OS X.

Address Book features built-in support for sync'ing with Google Contacts but it's not been made clear by either Apple or Google as to what exactly doesn't work. Steven's useful list is non-exhaustive but is a good start in understanding what may not work.
