Chat while you email

My first hand experience in using Google Talk embedded with Gmail was quite impressive. This was something I eagarly awaited for, while they enabling in all Google accounts over a period of time. The contacts are neatly laid out on the left bar, while the email is still clearly the main intention of display. The chat window does not have to pop out separately, saving the clutter of open windows. I'm sure this idea has been around for a long while, but as usual it Google who thrives on innovation! Also, provides a big advantage of allowing you to chat inconspicuously while your boss may be still around!
