Microsoft Co-Founder Paul Allen is leaving that company's board of directors. Allen will formally leave the board on November 9, the day of Microsoft's annual shareholders meeting, but is expected to spend about the same amount of time working with Microsoft. Like Bill Gates, Allen is expected to move away from the company's day-to-day business operations to focus more on technology. "Being an active board member for a dynamic and successful company such as Microsoft is a time-consuming role and one I have enjoyed for many years," reads a statement from Paul Allen, "This new role will enable me to spend my time on technology and products where I can really make a significant contribution."
