Google Maps is testing a new way to view maps by integrating live shots at street level. It's called Street View. So far, only the big cities like New York, Denver, Miami, Las Vegas and San Francisco are up and running but fret not, more cities will be added soon. When you map a Street View enabled city, a person icon appears. Drop him anywhere to see a live picture of that area. You can move up and down the street and even rotate the your perspective horizontally. This combined with GPS navigation would be awesome. Com'on Google, if anybody can do it, it's you!
On a side note, I just called my friend to tell him I'm looking at his house.
