I think you somewhat misunderstood my point (and I think AES's point  
too). To put it in a nutshell: if you wish to use Mathematica only as  
a computational engine and use TeX, Illustrator and whatever other  
programs you wish to use for non-computational tasks, then you can do  
this just as well with Mathematica 6 as with 5 or earlier, and in fact  
much better, since the computational engine is now much more powerful.  
It has become much more powerful without any fundamental changes to  
the basic structure of the language (which is not the case with some  
other rival programs). So, if you do not care for Mathematica's  
typesetting, graphic and presentational capabilities you can simply  
ignore them - they in no way affect the computational ones. Indeed,  
this has to be so, otherwise the Kernel would not be able to function  
without the F.E. and it obviously does.
Your concerns about the FE becoming over complex for newcomers  
(whether justified or not) affect only those newcomers who need  
capabilities other than pulling down menus, copying and pasting and  
using Shift-Enter. If I am not mistaken, AES thinks that these are the  
only FE capabilities Mathematica needs. My point is that for users who  
adopt his approach (which I have nothing against in itself,  
particularly that it isn't all that different from mine) there has  
been no significant in difficulty and complexity. Even the complaint  
about the lack of printed documentation does not carry much weight, if  
all that you care about is the Kernel, since available documentation  
for earlier versions is more than enough to turn one into a (Kernel)  
power-user.

Finally, I would like to add one comment on the issue of WRI's  
"strategy" that AES has raised. Actually, this strategy has been very  
clear many, many years, in fact even since WRI decided to re-position  
Mathematica from a "system for doing mathematics by computer" (in  
other words a "CAS") to "fully integrated technical computing system".  
Note the words "fully integrated". To me it has been clear for more  
than a decade that this was meant to imply things like typesetting, a  
fully programmable graphic engine (independent of PostScript), and  
other things. In fact, any one who attended any of the numerous  
Mathematica demos, particularly those conducted by Theo Gray, could  
have had no doubt about this. Has this been a success? Well, let me  
point out that quite a large number of commercial general-purpose CAS  
have appeared since Mathematica's debut (and some even earlier). With  
one notable exception none of these has been a commercial success and  
most are available now as freeware. I would say that is a pretty clear  
vindication of Wolfram's strategy.
By all means have a discussion of the "product strategy" of  
Mathematica if you enjoy this sort of thing. Butif if anyone hops to  
stop or reverse the ongoing process of "integration" (as in "fully  
integrated") than all I have to say is that it seems to me to be  
rather late for that; by over a decade, actually.
