I heard a story about a company that changed the presentation of the search engine on their intranet site. Originally it was a simple text field with a search button.
After the technical team had finished making the updates there was a simple and obvious change to the text field.
Apparently without implementing Google Search Appliances, or indeed signing any contract with Google. The result was a marked improvement in the feedback of intranet users.
The story may be apocryphal, but if not it shows the remarkable positive brand value of Google.
