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.
