Within context, I was speaking with respect to the math on the ACT, in which
the HP can do anything and everything the TI can do.

Certain things are assumed here.  It would be a safe bet that anyone of enough
intelligence to require a graphing calculator can learn RPN in 5 minutes.  In
fact, they already partially know it, assuming they are stepping up to a
graphic calculator from a normal scientific calculator.  What sort of notation
do you think the TI-30 uses for trigonometric functions?

People appreciate different things.  This is called taste.  I guess some people
enjoy making extra keystrokes for parentheses.

Within context, I was speaking of productions of the user base, not the
professional designers of the calculator.  And this statement is true:  try to
find a counterexample.

Professionals (by nature of the term) do not innovate without a monetary
motive.  Whether TI pays or the user pays, when something is developed
professionally, the developers _will_ get paid for it.

Perhaps this was a bit of an overstatement.  Regardless, the creators of these
libraries do support their programs well.

Indeed, it is self explanatory.  In case the point eluded you, though, it is
this:  In 1986 HP released a calculator that was by and far better than any TI
calculator that was released for 10 years afterward.  Now, TI has released a
calculator that may be the equal of the HP48.  And yet HP will release another
calculator.  As I said before, based on past ecperience, HP's calculator will
be better than TI's calculators now and for years to come.
