No I don't use Bing but they are coming up with more innovative features than Google lately despite the fact it was a "Google ripoff" to begin with. Google's original search engine technology was exclusive but other sites have caught up with them.

Google's next major project is rumored to be a social networking site to compete with Facebook. They could be spreading themselves too thin like what happened to Yahoo, but their solution is to discontinue stuff that isn't working for them like Google Videos, Wave, and Gears to name a few. Possibly the same might happen with Android if something superior comes along.
