Google Earth is Free
Google Earth, Google’s mapping product formerly known as Keyhole, is now available as a free 10 MB download. Those with Keyhole can upgrade to this new product. The download page is somewhat cheeky, in classic Google style. Also in classic Google style is the (beta) label on the product.
I like maps and Google Earth appeals to the basic evil overlord impulse within me. Just check out this overview from Nathan Weinberg at Inside Google. The screen shots alone are worth the price of admission (that’s free in case you forgot in the last three sentences.)
For those who want even more functionality, Google Earth Plus can be yours for $20. If that’s still not enough, Google Earth Pro, Google Earth Enterprise, Google Earth Fusion, Google Earth Server and Google Earth Enterprise Client can really give you that ruler of the earth feeling.
