Re: enduring market for high end calculators- Message #19 Posted by Walter B on 10 Jan 2011, 1:56 p.m., in response to message #18 by Martin Pinckney
IMHO it depends on what you are acustomed to. While most people are taught parameters following function names like in f(x) or f(x,y,...), far less think reverse and even less write reverse. So SDEV(x,y,z,...) looks natural, while anything like x,y,z ... SDEV looks awkward to the vast majority.
RPN requires us handling only one parameter per step the reverse way, e.g. 3 ENTER 17 / or 123 STO 7, which seems being achievable at least for the many enthusiastic users of this logic - and even becoming natural after some training (else we won't find as many missionaries of RPN).
RPL further proceeds in this "awkward" direction, and apparently goes beyond what most people are willing to accept.
These are no statements about the qualities of the methods mentioned, only observations.
