I watched the video they had linked for an intro to the KDE desktop. I must say, KDE has become pretty slick now, and OpenSUSE does a good job with their KDE desktop.
Sorry to be so negative, but uggh... So much work has gone into KDE over the years and it still reminds me of 90's IT-guy art. From the rainbow colored icons to the cluttered layouts to the mixed light and dark themes.
I was actually more excited about the functionality of Dolphin, than the default theme, which is a bit dated. I have seen some people do some nice themes for KDE. Better defaults are needed, I agree.
