Starting with today’s update to MAC OS X Leopard, 10.5.3, which should come down to your Mac automatically in the next week.

You’ll see an option in Address Book to sync your contacts with Google Contacts, this is really good news, as many client’s already are using a combination of Gmail’s great IMAP and Spam filtering combined with Apple Mail, the big issue was that Apple Mail, and your iPhone/iPod uses Mac’s own ‘Address Book’ (not to mention your iPhone and/or iPod’s contact list), wheras GMail relies on it’s own Contact database. 

Well rejoice, you can now synce the two of them up and have one unified list of your contacts accessible inside a browsear window, Apple Mail, your iPhone, iPod Touch or any other device that syncs with your Mac, Moto RazR springs to mind.
