Mac convert, sync between Address book and Google Contacts

This article shows a complicated workaround - if you want to try this, make sure you read all the comments as well - to enable Address book and Google contacts sync. Why on earth Apple hides the Google sync option from Address Book's preference is anyone's guess. I find it incredulous that I have to edit plist to fake, and go through manually invoking a command on the terminal to get this working... Clearly this isn't something Apple wants to make users happy about.
