#2It's really interesting how calculator technology has stagnated over the years. I'm in a BC Calc class now where we are still using 89s. My teacher is aware of the nspire calculators and he frequently uses WolframAlpha but hardware wise, he still teaches off of the 89.

With straight calculators, I don't know if there's a whole lot better for them to get than the 89. For anything more advanced than the built in computer algebra system and BASIC can handle (which goes quite a way, the CAS is really pretty good), you'd likely want to do on a "real" computer anyway, strictly for interface (screen and keyboard) reasons.

Calculators can get / be WAY better than the TI-89. Look at the HP-50g for starters. (Insert TI vs. HP) / (Algebraic noation vs RPN) battle here

#6For reference, a TI-92+ has a 12 MHz Motorola MC68000 processor and 188 KB of RAM.

#7I'm a long-time user of the TI-89 (through hs, college, and now for business accounting) - has anyone solved the input problem? The keypad is only good for arithmetic and symbology, typing text is pretty awful.

If it's really Unix-like, it should be possible to attach a VT-100 to the serial port ;-)
According to http://punix-os.blogspot.com.br/2012/03/floating-point-grays... they want to add support to PS/2 keyboards through an adapter.
This http://education.ti.com/educationportal/sites/US/productDeta... also seems like a good solution.

#9How about the old Casio PB-700 up to the PB-2000 that were programmable in Basic, C and Prolog?

Why do you say the HP-50g is so much better? I own one, but because I also own a copy of Mathematica, I end up using the HP only for in-class exams and such. The hardest work it gets is a few tricky integrals.
