Sure, Google Earth is cool. I paid them their $20 and the new 15m imagery is slick. I can see how a savvy real estate agent would dig it.
But have you seen Amazon Yellow Pages? Google is driving all over the country using lasers to figure out how to make 3D images of buildings (not sure why that's useful) but Amazon is driving around taking pictures out of the windows of a GPS-enabled Red Truck. No 3D, nothing fancy, just JavaScript and a LOT of pictures.
Here's Amazon's view of the Benson Hotel in Portland. Make sure you click on the "Walk up and Down the Street" buttons. Weird eh? They even have a "click to call" link where they will broker a call to you, because dialing the phone yourself would just be too hard.
There be some interesting stuff going on. Next step, Virtual Earth.
