Quick TI Thoughts
Calculator Succession
TI-86 -> TI-NSpire CX -> TI-NSpire CX II
TI-89 -> TI-NSpire CX CAS -> TI-NSpire CX II CAS
What do you think? I think the TI-Nspire has more than a TI-84 Plus, at least in complex numbers and Boolean conversions.
The CX II adds Python. The non-CAS does neither have a computer algebra system nor an exact answer engine (can return answers in terms of pi or factor square roots).
------------------------------------
Also: why do the TI-Nspire non-CAS and TI-84 Plus (CE) does not have an exact answer engine but the TI-36X Pro does?
Future Dream Calculator? The TI-84 Solar Edition: basically the TI-36X Pro plus graphing, programming (at least TI-Basic). The TI-36X Pro already has a battery backup.
