Fortunately the Squeezebox Server / LMS runs well on Windows Server 2008 R2, which means it will run smoothly on Windows Server 2012/Windows 8; up to a couple of releases ago, that was not the case.
For those who are using the server on Windows boxes like me, that's not too bad in terms of longevity (especially true if Logitech keeps the promise to keep supporting it for a while). Same goes, I think and hope, for Linux-based servers.

I am really sorry new Logitech clients (usually excellent hardware, in my experience) will not connect to LMS any longer. They lost me as a customer on that.

In my case, this makes the HTPC venue and even more attractive one.
