The axiom version that exists on windows is still in alpha form and
is somewhat behind the linux version. Some of your difficulties are
due to this and some are just things we need to fix and document.

We're trying to address this issue with documentation. We have split
the book up into 4 volumes (tutorial, programming, reference, developer)
in order to focus the information for the target audience. The new book
volumes are still in development and should address this issue.
Once we get the documentation stable we can publish it. We have found
a "print on demand" website (lulu.com) which will allow people to order
hard copies of the documentation so people do not have to work from the
online versions. Of course, the online versions will still be there.
We're also experimenting with "installer" programs. I'm not sure when
you got the windows version but there have been a couple iterations
at improving the installer scripts so they work smoothly. Any feedback
you have is most helpful.

Ah, well, that's actually been a point of discussion. I'm in favor of
packaging TeXmacs with the install script but the developers are not
all of the same mindset about this. I've forwarded this comment to
the developers list and we'll address it with documentation and
possibly combining TeXmacs into the install.

This is just a mistake which we'll correct. I understand that it is
discouraging to have trouble getting started but it's very hard to
know where the tripwires are for new users. I'm nearly blind to these
kind of things because I'm too involved in the process to see them.

Yes, it's certainly a difference between axiom and the other systems
like maple and mathematica. Axiom is much more tailored to the
computational mathematician. Maple and Mathematica are "engineering"
systems. The downside is that Axiom's type system does make learning
the system harder. The upside is that Axiom is better both in terms
of its mathematical structure and its programming structure. In the
long term Axiom is where all of these system need to go.
In terms of student use Gilbert has defined a project to simplify
the use of Axiom considerably (the so-called "zero learning curve"
interface) which we are just beginning to work on. It is in the
axiom--zlc--1 branch and is nowhere near ready to use. Myself and
two graduate students in CAISS are working on it.

The windows branch does not yet have the graphics or the browser ported.
Currently that code uses X11. We're looking at numerous ways to get that
code running in a more portable manner but it hasn't happened yet.
The February 2005 release of Axiom on Linux will have the full graphics
and browser (which just came to life over christmas vacation) available.
Gilbert is looking to develop a linear algebra course that uses the
browser technology with axiom as an experiment. That is also "in
process" and not yet ready to show.
