Even though he's no longer a CEO--or even a full-time Microsoft employee--Bill Gates managed to score an invitation to and speaking gig at the company's CEO Summit this week.
Among the other high-profile guests at the Microsoft event were Wal-Mart Chairman Rob Walton, JP Morgan Chase CEO Jamie Dimon, and IAC Chief Executive Barry Diller. The event runs through Thursday at Microsoft headquarters in Redmond, Wash.
