Like SBS 2008, EBS 2008 comes in two editions: Standard is $5,472, and Premium is $7,163. Meanwhile, for midsize businesses with more sophisticated IT needs, Windows Essential Business Server 2008, previously code-named Centro, offers a range of additional messaging, management, and security tools. Companies that purchase SBS 2008 will pay 30% to 35% less for the bundle than if they'd bought à la carte software, said Steven VanRoekel, senior director of Windows Server Solutions, who added that companies also will save through utilizing the software to create Web pages or performing IT duties. The 2008 version is updated to use 64-bit Server 2008 and Exchange 2007.
