With the recent acquisition of the Picasa photo program, Google also get the hand on the Hello Instant Messaging software. I was very surprise that nobody make the link with that acquisition and the Google toolbar !
Imagine a new Google Toolbar with a IM (instant messaging) capability and with your Gmail account integrated. After that ? A Google Deskbar integrated with the Picasa technology to search the Web (and Google Image) and your computer for pictures and files!
