Windows Home Server
I beleive Dell would gain quite a few customers both home and smb if a Windows Home server was offered. There are a lot of benefits running a windows home server. For both home and smb the ability to backup your systems daily and if required you can do a total restore and your system is back to the way it was. Also media streaming, a central repository for media files. The list goes on. It doesn't need high spec hardware to run so cost could be kept down.
