The new Google Instant search reveals streaming Web search results as fast as you type. As awesome as the concept might be, though, the results are confined to the Web. Google has the elements--combining Google Instant with Google Desktop--to develop a universal search capability that can drastically improve productivity.

Marissa Mayer, VP Search Products & User Experience for Google describes the advantages of Google Instant in a blog post. "The user benefits of Google Instant are many--but the primary one is time saved. Our testing has shown that Google Instant saves the average searcher two to five seconds per search. That may not seem like a lot at first, but it adds up. With Google Instant, we estimate that we'll save our users 11 hours with each passing second!"
