how well does Address Book sync with Google contacts? I have always been hesitant to try it as I am not sure what it will do when it first tries to sync: will it replace the google contacts? merge them? replace itself with google's contacts?
there also doesn't seem to be any indicator of sync status or when it was last synced successfully so I can never tell if it is actually synced. Does it need to be open to sync? will it sync when it first launches? what is the generally speed with which it syncs with google?
