It's not clear to me why Google has to be broken up. Google built the best browser around, people aren't using it for no reason, and then it used its user base to direct them to their search - which to me sounds reasonable (most people would use Google for search even if they're on a different browser. Whether it's habit or simply a superior search engine - that's what they want).

Making Google sell chrome, to me , wouldn't be different than making Nvidia sell a big part of their GPU know how or making Microsoft sell Windows or making Apple get rid of the App Store.
