This is a little bit late but I still recommend you watch this video because of its wow factor and inspirational view of the future in the next coming years.
Things to take note
-Watch how Microsoft Dynamics deliver richness for better collaboration.
-Watch Bill Gates demonstrates the future of software and hardware.
-Watch how Bill Gates responds to the question and answer forum.
As far as 2006 is concern this keynote is by far the best among them.
