Brief review:
Google Desktop still takes long time to index the files but the CPU load seems lower than beta version. Google Desktop will cache your visited website(even secured pages) and display screenshot thumbnails in search result. Too bad, it still does not display preview for image file.
Other Free Desktop Search Tools:
According to CNET Review, Copernic Desktop Search is the best among all.
