Auditors at CME Group have the crucial job of confirming the financial health of the firms that clear trades for its members. CME Group is piloting Windows 7 slates, which run the full Windows 7 operating system and can run business applications and access network resources. CME Group supports the slates with its existing infrastructure and expertise. Porting an application to Windows 7 slates takes only 8 percent of the time that CME Group estimates it would take to port to another tablet. The company, with the help of Microsoft partner Clarity Consulting, built a touch-enabled prototype for Windows 7 slates in just one week. It estimates that Windows 7 slates could increase auditor productivity by 10 to 20 percent.
