Is Microsoft getting serious about Mac customers? After launching its own PC vs Mac comparison site, the software giant has now released an updated version of its Windows Home Server (codenamed Vail) which is used in networked storage appliances such as the HP MediaSmart Server. The new version supports Mac computers natively. In the past, it was up to vendors like HP to add stuff like Mac support and Mac-based administration features. If you are not familiar with Windows Home Server, it is a custom version of Windows Server 2003 that is designed to power storage appliances. Customers can also buy it and build their own PC-based servers
