The really scary thing about the 89 is that it will be allowed on the AP
Calculus Tests.  Anything that can do symbolic computation, especially
derivatives, antiderivatives, DifEq's, etc. (not that this is a bad
thing) gives an unfair advange to the person using it.  Of course, this
kind of thing was probably said about graphing calculators on ordinary
tests...
Anyway, the TI-92 non-plus is still forbidden, even though the 89 does a
lot more. This is strange.
