What some have to realize is the simple fact that Bing and Google are simply related to one another in terms of their "searching capability". Believe it or not, this service, offered by both providers is minor in perspective to the bigger picture. Google is MUCH MUCH more than simply a search engine. Of course it's search capability is the front end service for most users, but Google itself represents a whole lot more, that in my opinion, will never be overthrown by anyone else. Call me optimistic, but I truly believe that has monopolized its industry and continues to do so.

In terms of just "search engines" I still think google will win this race. Being such an established enterprise, I think google will continue to upkeep its market share (if not increase it). Google has become so strong in its image, that it is now a household name across the world. I'm sure you've all heard someone say "Oh let me Google that".

And of course Microsoft can throw money at Bing all they want, but I highly doubt that'll put a dent in Google. To me, this bing vs google is more of a david vs goliath type of war. Google being the latter of course.
