Google for legal research

For several years I've done basic labor and employment law research on Google. Its not for everything, its not where you can Shepardize (need Lexis for that) and necessarily search for the latest decision, but when you want to grab a case or generally search a topic, it's been pretty good. Its also easy to use and the searches seem to return more of what I want than the premier research sites. Good just got better this week. Google now provides federal and state caselaw and access to legal articles through Google Scholar, and, uh, its free.
