also what was the point of metro'ing the server as well? im pretty sure admins don't need such an interface..
I think it makes more sense than supporting two different UIs. It is sub-optimal as a server interface, but that doesn't really matter, because:
powershell with ZERO GUI
This was the biggest jump ahead for Windows Server since NT came out. People have been asking for a non-GUI version of Server forever and now we have it. This is extremely beneficial to the majority of enterprise customers who script and deploy their servers as VMs these days and who, frankly, don't need (or want!) any sort of graphical admin capabilities running on the server which just waste resources.
I'm was much more excited about Server Core than I am metro. ;-)
