Is RPN still relevant?

[bxparks]

I find this thread, and the old threads from Valentin, very interesting and informative. I hadn't paid attention to calculators since around 1990 until recently. So my personal take is:

- algebraic: good for students who are learning math; most popular because Education is the biggest market
- RPN: still relevant; a practical tool for people who have already learned the math
- RPL: more consistent but too complicated; and dead, since no one makes them anymore

(I had a longer version of this post, but the browser ate my homework, so I'm posting the short version which is probably better.)
