RPN/RPL is still relevant

Is it already dead?
I doubt very much that HP will continue on that path.
For me, at least, HP did miss the oportunity to rebird their Calc´s business stay with a obsolet programing language.

Anyone who works in finance and does a lot of number crunching (even the clerk behind your bank's counter) will likely be using RPN machines -- though not necessarily from HP. Even some cash registers operate in RPN. A new calculation starts by clearing registers to 0, and then one proceeds to add (for example) by typing in a number and pressing + and repeating with another value followed by +. Because the interface is always buttons (for each digit and the basic four operations), input efficiency is a must and there's no beating RPN when it comes to efficiency.
