Dave, try this link on the desktop to see Google's Street view. You can tell what time-frame the photos were taken by what movies are playing at that theater. Sometimes I zoom in on the people to see if there's anyone I know. Actually, I use the street view sometimes to see what the storefront of my destination looks like.
However, I use Live Search Maps and Virtual Earth 3D more often. It's just so much cooler to zoom through the City in 3D!! I've also used that in Photoshopping the old WTC out of an image for a client piece... I needed to see if any other buildings could be seen behind the WTC once it was taken out.
Both are useful in finding safe places to park my motorcycle on evening trips into Manhattan.
Having the Virtual Earth 3D being part of Live Search Mobile would be rediculously cool, but I don't think our little mobile devices will be able to handle that just yet.
