Windows Home Server 2011 and Windows Server 2011: Essentials has been released on TechNet and MSDN. I’m still undecided on which one to go with. I’d really like to run a domain in my home/home office and am a bit upset with the lack of Drive Extender. So, I’m thinking of skipping the WHS this round (I love the older version of WHS, which I am running now) and going with a full server product.
Look for the WHS available on OEM machines in Early May, and the Server 2011: Essentials to be available on store shelves around the same time!
