I`m really starting to like Bing.
"...just a few days ago, Bing revealed they too like Google are building a "massive index of apps and app actions" to help users discover content within apps. The announcement covers two parts: app link markup and using schema.org to power app actions."
APP LINK MARKUP:
"When a search takes place on Bing that returns a page containing the above meta tag on website to content in app, Bing will make the decision to show a link to the web page or the app in its results. If the app is chosen, the user will be directed to the specific part of the app that contains the content the user was searching for. In this way, Bing`s experience works very much like Google`s App Indexing API experience."
APP ACTIONS
"Bing takes things a step further by incorporating "actions" into their engine using metadata from schema.org. For example, if a user wants to listen to an audiobook on their drive home, they might search for "Listen to Coraline" by Neil Gaiman. If a site like audible.com added metadata to their Neil Gaiman webpage that specifies an action like "Listen" with a link to the location of Coraline within the app, Bing could send the user into the audible app to start listening to that exact book."

That can be huge for xbox and Windows Embedded Automotive (Ford SYNC for example) because both are powered by Bing. Duane Forrester blogged about it last year:
