iAddressX gives you menubar access to the 10.2 address book, allowing you to highlight any name and open a new email to that person. It's a slick, easy to use application.

The reason it only gets seven stars is that it chokes pretty badly on large address lists; when it goes to display the "All" category, things just lock up for quite a while. But if you don't have many contacts (I keep a couple hundred or so), it's a very handy utility.
