For many sysadmins Hyper-V Server is an area where Microsoft's TCO and ROI documents - built around the "Hyper-V Server is free" market-speak - fails to align with reality.
If you're a PowerShell guru – or willing and able to use Windows 8 – then Hyper-V server mostly lines up with the Microsoft pitch. If you're a PowerShell and Windows 8 refusenik then rejoice because the third-party developer community is here for you.
