That's a fairly vague statement. Not new, but I don't see it losing much of its unspecificity with repetition.

These are all signs of a healthy work flow.

Still sounding quite solid.

This last is out of line. We have, as a company, consistently tried to put solid technology into the hands of our users. Calling this monomaniacal is an insult to some really good work (and the people behind it) that has gone on for a number of years. Sure, there's been some bad work in there, and some real missteps. Some indeed has happened in areas you like to bash on, e.g documentation. There have also been consistent attempts to improve that which can be made workable and/or better.
As for the specific areas you mention, it is certainly true that effort has been put into all of them. It is also true that the level of success has varied, and in some areas we are probably relatively weaker than we have a right to be (though of the ones you mention, I'd say only one or two at most are anything below state of the art).
I will also mention some of us have a very different work flow from yourself, and manage to keep a considerable amount of material e.g. presentations and electronic papers, in Mathematica. That is to say, while the tools you use work well, I think the ones I use also have their place. I'll also mention an area you omitted, the development of an IDE. That too has taken considerable effort and has had, I think, commensurate success.

Fair enough. The main point of Manipulate was to shield relative novices from the sort of detail in Dynamic functionality. By "relative novices" I refer to us (as in you and me).

First I will say that I also make PDF copies of my Mathematica slides, and for this very reason. So far I only had to resort to them once, when my laptop had a disk failure at a workshop. Someone actually did download and install Mathematica Player, whereupon we learned it would not toggle between display modes (I had left my slide show in Working rather than Slideshow mode; I do not know if this Player deficiency has since been addressed).
Clearly Power Point and other common formats make sense to retain, and for the reasons you give. But that does not mean Mathematica slide shows are useless, and indeed one can do quite a bit with them that cannot readily be done in other formats. Of course the reverse is true as well. That's what makes for a horse race. And better technology.
