7. Voice actions
Windows Phone 7 has speech recognition, and the iPhone benefits from an application that Apple bought called Siri, but neither has integrated it into the phone nearly as well as Google.
From any screen, you can hold down the search button for a few seconds and a voice menu automatically waits for a command. From this menu, you can write an email, SMS, pick a song, navigate to a destination, initiate a call, search the web--just about anything. This is a game changer if you want to use your phone in your car or you want to walk without having to type.
