I took an exam today where only TI calculators were available. I felt I was caught between some older models where the TI interface was not quite worked out.
And I don't see much progress then trying my daughter's TI-84.
I am a decidedly non-mathematical/non-engineering person, but have loved RPN calculators since I bought an HP back in the mid-1970s. RPN is just natural to me, even doing basic arithmetic. I use PCalc in RPN mode on my iPhone.
