A built in RSS reader. I almost think I could dump Google (except for plus, which I still think should be built into the people hub, and except for Voice, because free texting from your computer is awesome) if I had a Bing alternative to Reader right on the phone. I have used Wonder Reader and it's very nice, but kind of slow. I am kind of surprised, considering how much "me too" stuff the big three engage in (meaning Apple, Goog and MS) that Microsoft has no RSS reader.
