Again, I want the emphasize modern “natural” entry as Casio calls it and “MathPrint” as TI calls it, that allow you to enter a problem as shown on paper. I’m not taking about single line algebraic entry. Sadly a lot of advanced graphing calculators don’t have this entry style on dedicated keys and require entering submenus to access these entry styles. Of the TIs for example, only the French TI-83 premium CE has a dedicated MathPrint fraction entry key. Most scientific calculators have this, both in Casio and TI, it is common place. For me, this is what broke RPN. No matter how good the DM42 is, it will never afford me the speed, ease, and flexibility that my TI-30X Pro MathPrint gives me, even with just number crunching.

I think it is ironic that the first calculator to allow natural algebraic "textbook" entry was the HP-48SX in 1990.
