Is RPN still relevant?

[Maximilian Hohmann]

Hello!

First, let me please say this to everyone who contributes here: I really enjoy this thread because it is about the very essence of why I spend so much time and money for calculators. What is it that attracts us/me to certain models and why does the same not apply to every other human being? And this is the real question here! Not I you or I like RPN, but why did so few other people like it, so that it is now on the verge of disappearing? And can anything be done to resurrect it?

What I also like in this thread - and in any other by the way - are the off-topics like this:

Thomas, I guess you have not driven an electric car yet ;-) Computing the range and charging time is not an exact science. You can discard 4 of your five decimal places or easier still, do the entire calculation mentally with just integer numbers!
Lots of traffic on the road so that you can only do an average of 60km/h -> 30km more range. No traffic on the road so that you can do an average of 100km/h -> 50km less range... Your wife says "it's cold in here" so you turn up the temperature by 3 degress and switch on her seat heater -> 40km less range.... You come to your car and find the windscreen frosted over. No need to scrape that off or wait till the engine is warm enough to melt it in an electric car - just turn on the electric windshield heater and defroster and two minutes later the car is warm and the windows are clear. I can even do that from my mobile phone remotely. Pure magic and one of the reasons why I will never ever want to drive a petrol car again. But it comes at a cost: 25km less range...
During summer (say June to October, because I only got it in June) our car consumed electricity at a very constistent rate 12,8kWh/100km. Now in winter it varies between 14 and 20kWh/100km, and quite unpredictably so. Not a mathematical task that requires decimal places!
