At long last, Google Earth — which has been demoed at several TEDs in different contexts — has been released for the Mac. TEDsters got an early glimpse of Google Earth at TED2002 when Dan Dubno gave a fly-through of its previous incarnation, Keyhole. And Domus editor Stefano Boeri used Google Earth to explore the future of architecture at TEDGlobal. The PC version has been available (in beta) since May. Now, finally, Mac-using TEDsters can share the eery exhileration of zooming in from outer space to the corner store.
