Question: have you ever visited this webpage?

For many people it is enough to be totally creeped out about Google.

Also, that Google remembers context can be handy but it is not essential. Without context, I am sure you would be equally capable of finding what you are looking for, although it might take a little more typing since you'll have to supply the context yourself. Imho, convenience is not a good argument for giving away your personal information.
