Re: Not too sure
and even then, there will always be something that just can't be done without the GUI.
From what I've been told, as of Windows Server 2012 not only does the GUI just act as a front-end for Powershell but most of the time it actually tells you what command it's running. So if you're paying attention you can point and click once and it writes the script for you. And in 2012 you can install the system with no GUI at all (as a server should be in my penguin-addicted opinion).
