Google finally launched its secretive desktop search effort, formerly codenamed Puffin and now dubbed Google Desktop. It allows searching through documents such as Microsoft Office files and other hard drive files, sorting them in the same interface, with most of the same features, as the Google web search. The PC-only application is available for download now, but it does not yet work with Google's on Gmail email accounts. Contextual placements from AdWords are not yet appearing in results, but they are slated to start showing up with the application gets out of beta.
