And what education level has Your ``first-time user'' ?
high school ? under graduate ? master ?
WRI promote Mma on a wide range of educational levels. The high school
user will probaly expect a level that is different from the research
scientist who had worked with Maple or MacSyma and now switches to

Yes ? really.
Why every pocket calculator is a acompanied by
a nice booklet called ``Manual''. The manual tells
the user how to use parenthesis, the angle units, the radix base.

And if You don't know what is reverse Polish or plain ?
Unfortunatly the TI-38 has not it's own news-group.

Yes but than is is nothing more than a pocket calculator. A quit expensive
one. You need a large computer, a operating system and Mathematica.

Yes it is hard to use, it deals with complicated thinks like
- differential equations
- 3d graphics
- indefined integrals ...

When I see this type of questions my firts idea is allways to reply
RTFM (``Read the ....ing manual) but I can't remember that any one has
get that answer.
The ``Mathematica Book'' is one of the best manuals I have ever seen.
It is well written and easy to use for a beginner as well as for an expert.
But the problem is that only a few people read it. Ok now it's a bit heavy
and splitting it into a couple of smaller ones may help. However
if a user doesn't read the manual, he will not be able to use
the pocket calculator as well as Mathematica.

I use only MS-Windows from Microsoft and it seems that it is extremly hard
to use. Did You ever search the registry ? Fortunatly my MS-Windows manual
(that came with the CD-ROM) has only ca. 20 pages. Unfortunatly the
``Windows resource kit'' (the true user manual) has the same expansion
as the ``The Mathematica Book'' but it is mutch harder to read.
Some years ago I was looking for a computer algebra. Because my nice
old muSIMP where turned into DERIVE and was less powerfull. I compared
Maple, MacSyma, REDUCE and Mathematica (it was version 1.x) and the
clear unifyed design of the programming language and commands let me
choose Mathematica. In fact the beauty of the language design make
Mathematica easy to use.
It might be a good idea to put some people from the street say
- a police men
- a house wife
- a school boy (age 9 or 10 years)
- a taxi driver
an let them perform some tasks like
- solving an integral equation
- solving a partial differential equation
- drawing the Riemann surface of a polynom equation of order > 5
- find the eigenfunctions of a helium atom
monitoring the mistakes will make Mathematica also more intuitive.

I am not afraid that Mathematica stagnate. With version 3 it becames
a serious platform for scientific publishing, it was already a tool
for computer graphics, and for computer algebra and programming.
This are all large fast developing areas of research. As long as
Mathematica stays on the top of all thease areas there will be no
