I wonder if they could be convinced to place Derive into the open
source community in order to further progress this wonderful
scientific tool (and I mean that in general for all CAS efforts)?

It seems odd to me that they would ever think that a package like this
was competition for a calculator - and maybe they were thinking of
merging the symbolic engine or a subset in the calc - but that doesn't
appear like it will work in this decade and the next (not enough
horsepower yet).

I wish that more of these would combine the benefits of all the others
and create a mega-CAS project which includes all the wonderful
packages that include such topics as number theory, abstract algbra,
algebraic geometry as well as all of the standard topics we all know
and love.

Two attempts to download SAGE here

http://www.sagemath.org/SAGEbin/microsoft_windows/sage-vmware-2.6.zip

ended in an incomplete/broken zip file of about 95 MB.

" I wonder if they could be convinced to place Derive into the open

Not likely. That would be giving away an asset and TI doesn't give
away anything. They don't even give away information unless it suits
their purpose. For example, from time to time people ask questions on
their nspire site, such as does their download software called TI-
connect work with the new calculator called nspire. Such questions
simply get ignored. If and when they want you to know something you
will be told. It's a strange culture.

(TI, HP, Casio, ...)

Although now rare in college and professional settings,
graphing calculators are still common in high-school math
education. But as full-scale computers become cheaper,
smaller and ever more ubiquitous, the future of standalone
calculators is increasingly unclear.

As the world's broadest and deepest mathematical system,
Mathematica's computational capabilities vastly exceed
anything that can be achieved with a calculator - and
provide a completely different level of educational
possibilities.

While calculators are easy to use for simple operations,
they rapidly become unwieldy when many steps are required.
Mathematica, on the other hand, is immediately able to offer
a fully scalable interface with dramatically more compelling
graphics and interactivity, as well as greater systematic
learnability.

With its unique document-centered interface and full support
for symbolic mathematical notation, Mathematica provides a
complete environment for educational computing, seamlessly
combining math, visualization, interactivity, programming
and text.

With support for the latest interface and presentation
systems, together with immediate access to thousands of
student-modifiable interactive educational demonstrations,
Mathematica redefines the role of calculation in the classroom.
