What blows me away is that this guy (and a few others) changed the world, but he doesn't have an ounce of arogance in him.  Equally impressive is that he doesn't aspire for the spotlight, but is passionate about continuing to make a difference with what he's doing now.

This was the best hour I have spent!  Marc talks about the importance of focusing on customer needs.  No wonder Microsoft is what it is today, built on these kinds of values.

Incredible stuff.
