Now... I like Windows 8 and this legendary Metro UI. It's not too bad but can be better. Never mind.
But story with Server 2012 is other. UI is very very bad. Appearance (including colors, themes and other) is tooooo awful!
That can be very better! Server 2003 and Server 2008 & R2 is much better.
Maybe I will try it, that was RC when I tried.
