HP's offerings are shockingly bad. They require multiple
keystrokes per digit to enter hex numbers and switching bases
is completey cryptic. On the the 35s you press [base][7] when
you want base 10. If you want base 2 you press [base][8]. If
you want base 8 you press [base][3]. For base 16 you press
[base][2].

It doesn't even seem to be consistent. According to the
documentation, sometimes you press [base][1] to get base 10,
and sometimes you press [base][7]. WTF?

TI's offerings are also shabby but not nearly as bad as HP's.
They at least have a model where you can enter hex numbers
with one keystroke per digit.


Reading the replies given, I'm curious as to how hard it would be to
create a calculator from scratch. I mean, use an ARM7 for calculations,
one of those SparkFun Nokia 6100 lcds for display (would do graphing
too). I'm sure it would be awkward getting the keys manufactured so you
could perhaps use a PS/2 port and a mini-keyboard.

By writing the code yourself you could set-up keys and functions just
exactly how you wanted.

Anyway I don't really have the time to properly look into this, perhaps a
project for the future however. What do you think?
