I gave a very brief talk about this at SAGE Days 3. You can see my slides at


http://sage.math.washington.edu/home/moretti/days3/talks/calculus.pdf

if you haven't already. Currently, nearly everything that was discussed in
our thread has been implemented. Of course, for every piece that has been
implemented, it seems like we discover several other missing features that
we didn't think originally discuss.

Still, the basic functionality is there. I'm currently working on fixing a
few issues (making plotting work correctly, making a seamless transition
between symbolic and numerical computation, and fixing a lot of bugs). I'm
going to be sending William a patch very soon (by tomorrow) to be included
with the next version of SAGE. I can send you a patch as well, if you'd like
some more time to play around with it/prepare your talk.

I'm giving a talk on SAGE in a week and I might want to have a basic

As far as this goes, I use a mix of all three. The notebook is nice for the
reasons mentioned by others. The command line is nice for when I need to
just test a couple simple lines. The attachment method I use occasionally,
since for me, writing long pieces of code in the notebook is annoying
(indentation is a pain).
