I see that Windows Home Server 2011 has been released to manufacturing. So it should be available on the market in April/May.
I’m sorry, but I can only raise a faint cheer about this product. It doesn’t strike me as a major step forward from the original Windows Home Server, and in some respects – notably the removal of the Drive Extender technology – it is a step backwards.
What really gets to me is that Microsoft had the chance to build upon the base of WHSv1 as a server and media appliance that could be used by the average consumer, and they’ve thrown that chance away.
