Is RPN still relevant?

Yes, but these are the three financial calculators (HP-12C, 12C Platinum and 17BII+), hardly suitable for normal school but rather for business school. All the ones that could be useful for mathematics and physics are way over 100$/Euros.

The OP said nothing about math or physics, so my reply is still correct.

Also, probably most students in school today are not engineers, math or physics students, so these models are likely suitable for most of them, for real life that is. But not being certain exact models from TI or Casio, I agree that makes them utterly unsuitable for use in high school math classes.

And who's to blame for that? Neither TI/Casio, nor the various Governments, IMHO. It's lazy Math teachers, or maybe more clearly, lazy math teachers in the 90s and 2000's when it was easier for them to use what was used last year, rather than actually think and try using newer tools and devices. After 20+ years, all the authors had incorporated the old devices into their textbooks and now they're so entrenched even the device manufacturers in question can no longer innovate and introduce new models to move the teaching technology ahead. I've spoken with dozens of math teachers and not one of them felt it was reasonably possible to introduce new machines into their curriculum, fearing pushback from other teachers that don't want the boat rocked, etc. It's sad....
