SBS Essentials 2011 takes Home Server's simplicity (and the option to quickly deploy it as a headless server managed from a remote console or in the browser), building on top of Windows Server 2008 R2 with a simplified Active Directory management platform.

The biggest change between the beta and the RC is, of course, the removal of Drive Extender. It has been replaced by a Move Folder wizard that's intended to simplify moving data from one disk (or disk array) to another as you add additional drives to a chassis. Intended solely for use with server folders, it's not the zero-intervention approach of Drive Extender, but it does save you from having to use Explorer to move folders and shares (and also means you can use the console rather than having to open a remote desktop connection to your server).
