Google Earth

As a followup to my "Hunt for WMD's" post, be sure to check out Google Earth:

Google Maps is an awesome web application. But, if you're already connected to the web, and have a decent machine (with 3D graphics card), then load up this Lite version of the old Keyhole product, and enjoy all of the benefits of a rich desktop client!

At some point, Microsoft needs to stop trying to compete with all products. Competition is great for innovation, but I'm not sure if they can catch up with the GIS stuff that Google now has (especially after their aquisition of Keyhole).
