It's not just the UI. It's HyperV management being restricted to other 2012 boxes, Sys Centre SP1 being needed for cloud mgmt and still only in beta. Personally, I'd be a little iffy about a wholescale MS server rollout until SP1 comes along. As for what mates are telling me, they have their reasons and I'm only relaying what I've been told, and of those who will be using it, they will be going core only and PowerShelling everything they need. However, even for some server admins, having to choose between 100% CLI and 100% tiling monstrosity is too much.
I take your comments on board, but I would argue that they are not relevant in selecting an os for an N40L used at home as a media server.
I am thinking WHS is old news. Win 8 looks appealling, but I would consider Server software. If other PCs in the house run Win 8, then is Server 2012 is a fair choice?
