The high cost of calculators is mostly limited to ti - hp is largely out of the game for educational calculators.

Ti was incredibly smart in it's marketing of calculators as they encouraged text book authors to write their calculators into textbooks ..

The Japanese we're too foolish to replicate that strategy. They thought they could win on high performance and low costs.

They couldn't have been more wrong.

I find even the Japanese calculators seem to be somewhat overpriced for whats in them

e.g. Nearly $40 AUD (about $30 USD) for a Casio FX100 from a local office supplies warehouse.

Cost of production would probably be $5, and they have been churning them out for years, so there is no ongoing R&D budget

that's probably a case of inefficient market place or inefficient vendor: a FX115ESPLUS goes for < $13, a FX300ESPLUS for < $10 at walmart.com, lower when on sale.

hardly unreasonable. No idea how they are comparable.

Yes. Only 20 million people in Australia, mean we pay an "Australia Tax" due to insufficient demand.

This can usually be overcome by buying direct from China (eBay or AliExpress) and waiting for it to arrive on the container ship

Another reason for poor calculator sales, is the fact that smartphones can emulate a very capable calculator, so why would you want to carry both around in your brief case.

RealCalc is one of my favourites

.. but there are plenty of others.

.. having said all that, I am actually a bit of a calculator fan. As well as some classic Casios, like the FX-602P and FX-702P there is, somewhere in this house an ancient TI 30 and a Commodore LED 774D... and then of course there is this....

... no batteries required. :D

I had one of those old TI's with led display.

But my favorite are casios. a fx-39 from way back, and i still have a fx-82 that's working nicely, aside from the power on switch, almost 40 years after I got it. back then people were expecting 10-yr life for the lcd.

but my favorite is the 12c. I have about 10 of them laying around between my house, backpacks and my offices. that's a marvel of engineering.

I have one of those Friden calcultors.
It was working several years ago, but not anymore : I need to find which transistors had broken, but too lazy ...

There are almost all famous calculators available on android/ios (ie HP/TI).. My favorite is the HP-42S with 34digits precision :) (Free42)..

I took a quick look at Free42 and I must say, I'm quite impressed. I didn't think there were any free Adroid RPN calculator emulators. Thanks.. yet another toy to distract me when I should be working :D
