Google’s claim that search users have choice is “bogus,” Microsoft CEO tells judge

I think it’s incredibly simple to change search engines

It's not though, because the other search engines all suck. I have changed my search engine, but I still keep going back to google all the time because it's often the only way I can actually find the page I'm looking for.

Microsoft's claim is they can't create an accurate search engine because they just don't have enough users to have reliable data on which pages should be presented to the user. Google has better results because they have more users, and they will never lose that advantage unless there is government intervention.
