Today I've download this app on my Mac Book Pro. I do use every single feature on my mac but for some reason this thing about opening address book was not as friendly as I think it should be. Don't get me wrong, address book rocks, but I think this App makes it even more cool. Take a look at this video. BTW I don't know the company or the developers what so ever but I think you guys did a terrific job! I definitely encourage everyone to download this app and use it. It will make your life a lot easier managing all your contacts!
