I think GP might have been getting at TI89 level calculators, which have CAS. That's a significant feature in my book.

- jacobolus 11y agoThe CAS in the TI-89 is a toy compared to Maple, Mathematica, Sage, etc., and typing complicated expressions into a calculator keypad is something mathematical sinners are forced to do eternally in hell.
- bane 11y agoI'm talking even better, but designed with the TI-like way of doing math. Something Matlab/Mathematica-level, but with a more reasonable input interface than something like Python for Android. I had a TI-92+ I used for years instead of fighting with Matlab since I had using it down to muscle memory. It worked well enough (until I needed more pro-level tools). For example, adding better support for matrix math than the TI-89/92 series, and some built in image processing tools...the platform already even has image acquisition hardware. Or a line of USB connectable voltmeters or other data acquisition hardware. For field use, lots of people still use these middle-school calculators because they have a decent combination of power and an interface they've been using for 6-7 years. Heck, I use emulators for TI-83/85/89 on my phone for quick calculations in the field or when I don't want to have to fire up an overpowered tool. The CAS on the 89 is almost magic in lots of cases.
