Do these people have absolutely no direction? What the hell is going on there?
First they adapt GNOME 2 with a patchset from hell. Then they adopt GNOME3 elements, but write their own interface called Unity. Then they design a 2d look-alike called Unity 2D written using Qt. Then they drop it. Now they are rewriting Unity in QML.
It must be hell for their developers. Tomorrow someone might come in and say "Forget it boys, today we're rewriting everything in C# and FLTK". Who makes these decisions?
This "convergence story" they've been chasing is going to bite them in the ass.
