I have to agree here. Classic RPN with its weird stack lift behaviour is not intuitive.

The commands that are prefix rather than postfix (STO, FIX, ...) are easier to grasp but are still contrary to the pure postfix way.

I believe it would be possible to have a classic RPN without stack lift -- keep a separate command line which is parsed on ENTER and which only goes into X.
