On August 1, Microsoft officials said that Brian Valentine, long-time senior vice president in charge of Microsoft's Core Operating System Division, was planning to move to another part of the company after Windows Vista went to manufacturing. Instead, Valentine has decided to leave the company and join Amazon.com. On September 5, Microsoft announced that 19-year veteran Valentine was moving around mid-September to a Senior Vice President post at Amazon. For now, Valentine's team will be reporting to Platforms and Services Co-President Jim Allchin. Once Vista RTMs, Jon DeVaan will take over, as planned, as the new head of Windows and Windows Live development.
