But it is useful (Score 1)

Although I understand that we are discussing Rights and Privacy, I would also like to add a point regarding functionality. I read all the disclaimers at Google's site, and I installed the toolbar. It has very useful features, and for a frequent search engine user like myself, it is a tool that has its value.

As it was pointed out, there are many disguised ways to obtain personal information, and since Google warned twice during installation about the privacy issues, I was very aware of the risks I was taking. For me, it was worth the download.
