Get it now – the Google desktop, a means to search through files, emails, instant messenger conversations and your browser cache.
My quick run through with it last night shows that it knocks the socks off the search feature in Windows XP. In combination with Google’s web search capabilities, this desktop app could be a challenger to new tools like blinkx (although see what Om Malik has to say about that).
For Windows only. Pretty good detailed review and installation guide by O’Reilly Network.
Commentary on some media sites says this is aimed squarely at Microsoft and its ambitions in the desktop/web search market.
