Emailing a link to Google Maps from Address Book!
I posted a tip a few days ago about how to bring up Google Maps from Mail or Address Book. That is new to Leopard. There is another feature that can also be very useful in Address Book. It is called "Copy URL of map". You can get it by right-clicking on an address in Address Book. What this will let you do is copy the URL of the specific location in Google Maps and send it by email or IM without even needing to load it in a web browser.
