I haven't been impressed with an application or website any time recently as much as I have with Google Earth. Based on the Keyhole application (a commercial product by a company now owned by Google), it lets you fly around a 3D model of the earth, zooming from satellite view to practically street level. It uses satellite photos and GPS information to let you fly just about anywhere.
Combined with Google's search power, you can type in a phrase such as an address, company name or location, and it will fly over the world's landscape, softly coming to rest over your destination.
I especially like the ability to highlight nearby coffee shops. Hmm does it also do WiFi hotspots? That would be cool!
