The U.S. Army, for example, plans to move by year's end from Windows XP to Windows Vista, as well as from Office 2003 to Office 2007. The Army has already moved 44,000 of its 744,000 desktops to Vista and is making the move to bolster security, according to an Army News Service article. In a statement, Microsoft senior director Gavriella Schuster said the Army's move represents a significant undertaking. "First, they see real value in Windows Vista's improved security architecture," Schuster said. "Second, it shows large organizations have unique needs and timetables for deployment."
