Ralph,

    I really would like to understand your critical remarks somewhat
better.

It is clear that one can easily and quickly run the frontend irresponsive.
However, in most cases I know, this is actually due to bad programming
(from Mathematica's point of view) rather than an instable product.

One typical reason is that a command returns symbolic results where the 
programmer actually expected only numerical stuff, and quickly things get completely out of hand.  But how should Mathematica know that all this was not intended?

It is the tremendous flexibility and the many possibilities which
sometims get into the way, and as a consequence the frontend can not
handle the output from the kernel any more.

I really do not understand where you expect Wolfram to get "its act 
together". My experience tells me: A good Mathematica program may run 
for days without any instability. But my stupitidy and/or lasy 
programming can run it against
the wall within seconds. Mathematica as such is definitely not unstable.
(of course, sometimes there are bugs as with any other major (and minor)
software).

Michael
