I think for many of us, the ultimate Google should just be some form of "grep for the Web". Defaulting to case-insensitive would be the only "massaging" of the query that I'd consider a good idea.
You don't even want it to spell correct? That's pretty extreme.
My 8 year old thinks I'm old fashioned because I don't just talk to the google lady casually like she is my friend, when doing a search/asking a question.
I think for many of us, "correcting" the spelling is one of the biggest annoyances of Google search, and the main reason which forces us to resort to using quotes so often. When I search for a word, I want to search for that word, not some other completely unrelated word which happens to have a similar meaning to one of the dictionary definitions of a word a few characters different from the one I typed.
Usually that is one click to correct, which works for me.
I often search for things I don't know how to spell, typically a proper noun, and often specifically because I am trying to figure out how to spell it and that is the quickest way.
