Microsoft requires that every WP7-based smartphone have dedicated back, home, and search buttons. Their functions are all self-explanatory, although the search button operates a little different than what you'd expect from Android or iOS.
Previously, the search button allowed you to look for something within an application. The Mango update changed that behavior, though, limiting searches to Microsoft's Bing engine.
Hitting the search button and using Bing is not the same as a search performed in Internet Explorer. However, punching in a query brings up a list of results that, if clicked, does open a Web browser.
Finally, there are some added Bing services in WP7 that you won't find on your desktop:
- Local Scout: Provides information on restaurants, shops, attractions, and events near your current location.
- Music: Allows you to identify songs that are currently playing.
- Vision: Scans barcodes, QR Codes, Microsoft Tags, books, CDs, and DVDs.
- Speech: Voice recognition function (powered by Microsoft Tellme) that allows you to perform a Bing search, call contacts, or launch applications.
