Several months back, Google purchased a company called Keyhole. Keyhole made a desktop application program which allowed you to zoom around satellite images. Pretty cool stuff. The catch is that Keyhole was charing \$40/year for this software, if I recall. Well today, in case you missed it, Google released this product, rebranded as "Google Earth"....for free. It has all the functionality of Keyhole's application with the addition of Google's Local search and direction finder.
