Query: The Reverse Polish System is better...

My company purchased an HP 32E for my use in 1981. When my own calculator failed (after a very short life), I bought an HP 34C. Now that I am familiar with the Reverse Polish Notation, I will never willingly go back. I now teach college chemistry, and every semester students come to me to find out how to use their (predominantly TI) calculators. The current crop of TIs is (IMO) counterintuitive.
