OnLive launched its virtual desktop service for the iPad and was immediately rebuked by Microsoft over licensing issues with the Windows 7-based service. The company has switched from Windows 7 to Windows Server 2008 R2 and is now in compliance, says a report in Ars Technica. Windows Server 2008 and Windows 7 are based on the same codebase and can be configured to look the same, so users shouldn't notice any change in the service.
