Re: scripting and compliling and studio
@dried_squid, if Microsoft has brought a "GUI-less" version of Windows Server to market, I'm not aware of it. It's the sort of product that would be of tremendous interest to cloud service providers, so it will be interesting to see if it ever surfaces!
As for the GUI versus CLI benefits, my experience is that CLI is faster if you know exactly what you're doing and need to make specific changes on a repetitive basis. If you're trying to figure something out, or need to do one thing a single time, GUI works pretty darned well. And that glass ceiling? I think it was a very real thing five or ten years ago. Now, GUI knowledge is the default and will get you the job in lots and lots of places.
