If you ask me, then it's easier to change the default search engine on Chrome than it is on IE for example. Say you have IE as your default browser and have it set up to use Live search as it's default search engine, then when you install Chrome and run it it will say that it's default search engine is Live search and asks if that's OK with you. They will not force their own search engine down your throat.
