Another reason might be that HP is just too expensive
?
Good tools _are_ expensive :-)
Just 3 years ago I bought a scientific calculater
which also does
hex,octal, binary and has all the logic functions. Price : 5 USD new.....
I think I've even seen one in a 'pound shop' over here.
Admittedly no RPN, keyboard less good, but still fully
usable.
^^^^^^ ^^^^^^^^^^^^
That, however, is a contradiction in terms. A non-RPN [1] calcualtor is
never 'useable'
[1] Note that i made no comment about it being a 4-levle stck RPN
calculator. RPL is a form of RPN.
