Oh and Mustardy, that is for legal reasons not because they want to track you. Google isn't evil. If I show you the prices Microsoft is charging my company for the same services that google offers you will be shocked. In a 5 years time, my company will save if I recall correctly over 2 Million Pounds just for using google.
Google's job is to track and advertise. Bing does it too, Yahoo does it to and every other search engine.
Google is the only one that offers an operating system for phones completely free, Android and it rivals the much overpriced Apple rivals.
Google is also one of the few that have an absolutely awesome office to work for. here is a video from 4 years ago, I'm sure there are many other videos for other Google offices. http://news.bbc.co.uk/1/hi/technology/7292600.stm

Google's search engine works
Google is a company and needs to make money somehow, by advertising it makes money. That doesn't make them evil.
