I'd say that despite to what the Material Room is attached (Poser), it is an extremely powerful node-based material-shader system.  If you've tired of it already, you are either extremely proficient, intelligent, and easily bored or as illiterate as Gareee mentions (and I make no claims to much literacy myself). :)

Let's just say that there are only a couple of other 3D CG applications with this level of shader control (Pixels3D, from which this was licensed, and XSI, for instance).  What more do you want?

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
