> Here is a video of KDE's

KDE commited suicide with 4.0. After that, whatever they produced was basically irrelevant, because nobody could take them seriously any more. Nobody is going to bet anything on KDE because of the fear that they could pull another "lets throw away a perfectly working 3.5 and rewrite everything from scratch" again. The same applies to Gnome also. Gnome could have avoided the fate by learning from KDE's mistakes, but they screwed up even worse, unimaginably worse.

Fool me once, shame on you, fool me twice, and so on. They are the picture-perfect example of the saying in effect. For all practical intents and purposes, KDE and Gnome are dead now.
