Even as a happy owner of several recent Sharp, Casio, and TI calcs, it seems to me RPN is still the superior entry system.

First, even if the input method is linear, the burden of keeping track of parentheses is still an issue. Second, while stating the expression in VPAM (Casio), Write View (Sharp), or MathPrint (TI), you’re adding keystrokes by moving the cursor in any of four directions to place operators in the right positions of the equation. I know this sounds like I’m putting HP’s Equation Writer straight in the bull’s eye to shoot it down, that’s not my intention.

On the other hand, with RPN, the only keystrokes you need are the ones to calculate your expression

The difference is that you enter expressions in an algebraic system the way you'd write them. You enter them into RPN the way you'd solve them.
