HP 35s missing functions that could have been easily implemented

AnalogJoe, This is not the calculator you are looking for

Here are some insights as to why the HP35s was made and why it turned out like it did.

As posted by Tim Wessman: "The goal was to a) make money, b) fix the abomination that was the 33s (hey look! It has a modern shape and shiny colors! Look how cool it is!), and c) to give a nice improvement in capability and functionality while still meeting NCEES requirements."

Also as posted by Jeff O:
"In case you did not discover the reason for the lack of USB or other means to upload and download data: if the 35s had such capability, it would not and could not be permitted for use when taking Professional Engineer and Professional Surveyor examinations sponsored by National Council of Examiners for Engineering and Surveying (NCEES) in the US. The NCEES prohibits any calculator with such capabilities, and produces a a list of approved calculators each year for use on the following year's examinations (see: http://ncees.org/exams/calculator-policy/). The 35s is on that list, as is the 33s. These are the only rpn-capable calculators allowed on the test. Without the market driven by rpn-users taking the PE/PS examinations, the 35s might very well not exist."
