Here's my point. Google is gathering information about users of it's phones, email services, search services, and more (if not all) of their products and services. Sure, that can be a scary thing to some people and I completely understand that. But if you are not going to use Google because they know too much about you, then who are you going to use? Because we all know that Microsoft also keeps track of what people are doing and I hope that you are not naive enough to believe that they don't.
Look at the example below, where they have emulated the same Google experience on their own search engine. And Microsoft has been in the PPC game a lot longer, so I have to believe they are doing the same thing there as well. Think about it...
