Increasingly, you don’t need a GUI to get your IT Pro job done. Everything you can do in the GUI, you can do in PowerShell.
This is even more true in Windows Server “8” Beta. Not just because there are >2300 cmdlets. Now, you don’t even need mstsc.exe (Remote Desktop Connection) anymore. You can make “<that server over there><do this thing>” from your console without having to remote in to the box.
How cool is that?
