Is RPN relevant for American (or substitute UK, EU, China, Indonesian, 3rd-world, etc.) school children?

Sure, but unfortunately many of them don't know it.

As it seems to be clear that RPN sits in an elitary niche (those who know and those who don't;-) ,
I may narrow the question to: Is RPN still relevant to you (or me)?

For me, I can anwer that question with YES!
Be it an HP-32S, HP-41, HP-42S with traditional 4-level+LastX stack, or a more advanced RPN implementation like in the HP 48 (*) or some of its relatives.

Even the poor RPN implementation in the Prime may be sufficient for some.

An alternative and specialized RPN environment for the Prime is the RPN SurveyCalc by Jacob Wall.

(*) Don't confuse the HP 48 RPN stack user interface with the RPL programming system.
