I use Bing maps quite frequently as part of my work, and every time I load a new window with Bing Maps I have to either type in an address to view the location/area I'm looking at, or zoom in from a view of the country I am in to the state/location I'm looking at.
It would greatly improve my user experience if Bing Maps were to either:
1. Allow the signed in user to select where Bing Maps loads to each time it is opened; or
2. Using the IP address, zoom into at least the State/Region where the computer is located (as Google Maps does by default).
