Forgive my total ignorance; do the kids today not use HP calculators? When I was in college (+/- 1990), we all had HP calculators, and so thinking in terms of (+ 1 2 3 4) felt pretty natural.
Nope. TI graphing calculators are basically standard. TI-83 is standard in high school and a TI-89 is preferred by those who know how much symbolic manipulation and calculus can improve their grades. They both do infix order of operations.
I believe what is popular right now with new calculator buyers are the versions of the TI-83 and TI-89 with USB connectors and faster processors, I think they're called the TI-84 and TI-89 Titanium.
