Bing Maps Java SDK provides a Java wrapper to Microsoft's Bing Maps API. This allows developers to access the API's methods for searching for points of interest, getting driving directions, matching addresses to the map, and more. This project is currently open for adoption as the creator no longer has time to maintain it.
Microsoft has just released a new Silverlight version of Bing Maps that is full of new features and upgrades. Although it's hard to say whether this release of Bing Maps has "stolen the cool crown" from Google, the new features do provide some additional value for users. The "beta" release is not yet available by default, though you can preview the latest version at: http://www.bing.com/maps/explore.
