I usually hate to say what software products I use [since you can be 0wned this way :-)] But I started using this Watson tool from Intellext (http://www.intellext.com) and it got me to realize that information access doesn't end with Google. What, you disagree? :-) This little tool uses a different metaphor from the Google-induced "search and you will find"; it just finds it based on what you currently do. And the thing is addictively useful!
Watson by Intellext. Watson provides context search on the desktop.: "Why go searching when you can have results found for you? We're changing the game. From Search. To Found. "
