Re: TIB: TI-89
Two words: symbolic manipulation. Well, that and derivatives, integrals,
limits, summations, etc. The 89 is good enough that you can afford to be
lazy. It has a much better layout and home screen. Solving is easier, more
logical, and more simple. You can get exact answers instead of decimal
approximations. TI-BASIC on the 89 is so improved over the Z80 calcs that
it's practically a different language. And, perhaps most importantly, the
programs for the 89 are much better.
