I love Apple's Address Book. I inadvertently just discovered two cool things. First, if you have Skype installed, right click on a phone number in Address book and there's a menu that allows you to dial that number in Skype. The only problem is that I think you need to have a 1 before the number. After I stumbled on this, I typed in Apple and Address Book into Google, and I found this plug in to work with Google Maps and Google Earth.
Okay, now I need to do some real work....but while I am goofing around, I see that you can create Skypecasts and Ecamm now makes a recorder to be used with Skype. Must revisit this! I finally around to playing with their iGlasses software a few weeks ago, and it's very fun.
