Is RPN still relevant?

[ttw]

It's relevant for me anyway. Over the years I have broken one HP50g, lost one, and had one just die. I've got two now (I got one in today to replace a lost one.) I've got another that is partially damaged; the case has parts sticking out but it still works.

For quick implementation of ideas, the calculator is nice. If things work, then I'll go to the desktop and write a program, but that has lots of overhead (but runs a million times faster generally.)
