In order not to affect the poll result, please find hereafter the top 5 HP calculators, sorted by year of release and not by preference :
HP-97
HP 41C/CV/CX (though no wonder that all the voters did vote for the CX model)
HP 32S
HP 42S
HP 48G/G+/SX/GX
It is interesting to nothe that :
- out of 5 preferred calcs, 3 "recent" calcs are in the top 5 though prices go high for other models for which few or no votes were expressed (10C, 27, 01, 35 red dot, 70, ...)
- the voyager series, though well appreciated for functionnality, met very few votes
- all the nominates do have one thing in common : they are very powerful and are capable of various kinds of calculation, and are all connectable/expandable
- Excepted for the 97, all are LCD displays calcs...
I am under the impression that all the voters expressed their votes for the capabilities/utility of their machines rather than which one they prefer in their collection...
I need more votes to improve the accuracy and take better conclusion !
