Simon--
Looks like a fine piece of hardware, but my collection of older
and very expensive HP calculators are all still working quite well.
I have found this on-screen calculator to be very handy. It is on
my desktop computer as well as my notebook. It is shareware
and very inexpensive. You should check out http://www.dreamcalc.com/
It does lots of scientific calculations, plus financial, plus it does
a lot of GRAPHING, as well as having a lot of useful scientific
constants available. Lots of statistical functions, Base-N and
logic functions, and over 630 constants and 80 conversion
functions.
For a list of features try http://www.dreamcalc.com/calculator_features.htm
It works great on complex numbers and does polar plots. I am working
on the author to add Smith Chart calculations. Here are some graphing
screen shots. http://www.dreamcalc.com/graphing_screenshots.htm
I am just a very satisfied customer who got to know the author after
making some suggestions. He put in 8,000 hours on the project.
It not only can use RPN, but also modern algebraic or classic algebraic
entry.
The standard edition is only $19.99. And the professional edition is
$29.99. All features work in the shareware download and there is no
time limit. If you don't pay for the key it will occasionally remind you.
It is probably the best value for shareware that I have ever found.
