Really? Good you please provide any basis for this claim?
Actually, the main changes in Mathematica 7 as compared with 6 are the  
inclusion in the Kernel of additional functionality (Image Processing,  
Mupliprocessing), which were previously available as (expensive) Add  
Ons. The other changes, as far as I can tell after using Mathmatica 7  
for a few days, are rather minor. A notable one is elimination of a  
number of bugs and better stability (so far, anyway, I have not had a  
Front End crash, something that used to happen regularly with version  
6).

Not at all. For the reason, see above.

Really? I so happens that I just talked about it to my daughter. She  
is a post-doc at Genentech (she turned down Stanford because of the  
notoriously miserable conditions of its post-doc programs) and she  
told me that the image processing software she is using costs 20000  
dollars to buy and 5000 dollars per year to maintain. That's, by the  
way, "the standard" in the field.  So why is Mathematica "ridiculously  
and impossibly expensive" compared with that?

Congratulations. Presumably you consider these "good deeds", of which  
you are justly proud, which is why you are letting us all know. Or is  
there any other reason?

In what way us this supposed to certify to his competence in the even  
most basic usage of Mathematica? After all, you are a Stanford  
university professor and after many years of using Mathematica and in  
spite of the availability of vast array of books etc. concerning it,  
you have not reached the standard that would be expected of a first  
year undergraduate, who has taken an introductory course at some minor  
university.

Ditto.

Have you got any idea what fraction out of the total number of  
Mathematica users do these responses represent?

As far as I know, Wolfram Research is a privately owned unlisted  
company and there is no way for you to invest in it even if you  
wanted, so really this is besides the point. As for your last remark,  
however, it is a bit amazing. Do you mean you would really not advise  
"anyone", even someone for whom the only alternative was a 20,000  
dollar program with no printed documentation? Doesn't this sort of  
thing tell us more about you than about Mathematica?
