Google Earth adds street view

The new Google Earth beta came out today with some exciting new features. Now you can fly down from space to street level in one seamless swoop. With the new joystick feature, you can virtually visit New York and walk around Time Square. I haven't downloaded it yet (this laptop wouldn't be able to handle it well), but I'm anxious to try it out when I get home. I wonder what Google Earth will be like in 10 years or so. Will we have full blown virtual city tours for every major destination on earth? I would love to visit the streets of Tokyo before visiting Tokyo.
