Keith -

Comparing the beta product you have on your site (which is pretty cool in its own right!) to the "enhanced" virtual earth 3-D product, the primary difference is the way the image can be manipulated from a "view" standpoint.

For instance, with the current product, you can zoom in from one direction only, then to change the view direction, you must select a new static view and the whole map "blips" until it recreates the map -- but it's still a static view, just from a new direction. So the current beta is like a series of snapshots and the enhanced version on the horizon is more like a video camera.

The enhancement  allows a "fluid"operation and permits the user to view (for instance) a home from every angle. 

At least that's my take on the way it works and how the enhancement changes things.

Now, what I want to see is this product with the MULTI-TOUCH technology. With the new surface product, I'm sure that's right around the corner. 

Now, what I would like to see is the ability to do the map with multi-touch on my tablet! :D
