I just recently started using Google Maps. I've been a fan of mapquest for a long time, and never really felt the need to change. I've been seeing some advantages of Google, but then today I noticed the Street View button, and I was blown away. Evidently they cruised through some major metropolitan areas with a truck tricked out with some cameras. They recorded the images and now you can see street scenes for several locations.
It's really amazing. Here's the demo of it from google's site. JM
