It's almost as good as being there.
Google Earth was release for the Mac on January 10, 2006 -
What is it?
A place to virtually explore, search and discover... Google Earth combines satellite imagery and maps -- putting the world's geographic information at your fingertips. "Fly" from space to your neighborhood. Type in an address and "zoom" right in. Search for schools, parks, restaurants, and hotels. Get driving directions. Tilt and rotate the view to see 3D terrain and buildings. Save and share your searches and favorites. Even add your own annotations.
Drawback? You need OS 10.4 (Tiger) -- coming soon to a desktop or laptop near you (next year's OS).
