Cool, wish I would have had that.. The built-in spreadsheet-like
function is way too slow.. Of course, just entering a number and
hitting
<enter> had a darn slow response time (at least on my 48gx).. Probably
.2
to .5 seconds..

It's actually quite nice.. That way if you're copying an expression
from a
book or something you don't need to re-read everything you type to make
sure its correct (parantheses, order of ops, etc). Just look at what it
displays.

The symbolic calculus on the 92 is actually quite impressive - it can
compute
derivatives and integrals that I wouldn't want to touch.. The only
thing that
sucks about it is that it doesn't handle complex exponentials very well
- it
breaks them down into sin/cos. Other than that it is very slick.

I used to be die-hard CLI fan, and now I still prefer a CLI, but realize
that
GUIs are useful for some things as well.. I don't like MS, but Windows
has
a fairly well-designed UI.. Sorry, but X sucks ass as the default is
setup,
and I know you can configure the hell out of it, but I'm to lazy and
it's too
much of a pain to do so, so I use win for a lot of stuff. Plus there's
a ton
of extremely good win apps (Photoshop, 3ds, kai, etc).

Maybe you know my officemate (BS/MS ECE, German, something else) - his
name
is Brian Vanderpool.. Ever heard of him?
