Google Desktop Search

Google has released their own desktop/web search engine. I have been using the Lookout extension for Outlook and it has worked pretty well, but it has nasty problems with memory leaks. Google adds some nice features to the capability that Lookout introduced including:
searching Outlook, Word documents, Excel spreadsheets, text files, PowerPoint presentations, and, of course, the Internet.

Most cool. I'm just starting to use it, but I'm pretty stoked about it.
