Razor-qt is a brand new desktop environment based on Qt framework, the same development framework that KDE is based on. Though it is still in its infancy and, therefore, not as feature-complete as KDE or other well known desktop environments, it has a bright future ahead of it. And from what I have seen so far, it could be taking KDE and the rest to the cleaners in the very near future.

Compared to KDE, one thing it has going for it right now, is that it is fast. How fast? Very.
