What calculators are you guys using that aren't in academia anymore and don't need the "exam approved" limitations? Or are we all just using software on our computers now. That would be sad. (I've had a Casio fx-991EX on my desk for a few years, that replaced a broken Casio fx-991ES. Though designed for academia, its operation is burned into my brain at this point.)
We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).
Ti really needs to stop with the artificial product differentiation. There's no reason 15 years after the Nspire CX CAS came out that everyone of their calculators can't do CAS.
Honest question: Why do we need physical graphing calculators anymore? Can't this just be a phone app? That screen resolution for one is horrible for 2026.
Also I don’t know about you but these days I welcome stuff that allows me to stay away from the damn phone.
Genuine question, who uses these in practice? In my experience, calculators beyond the basic were always banned in high school and college, cause everyone's so afraid people might store something into them, and afterwards it's just matlab and python. It's not like laptops aren't a thing that everyone has on hand.

> What calculators are you guys using that aren't in academia anymore and don't need the "exam approved" limitations? I still have my TI-85, but I essentially haven't used it since I left college. For 99% of what I need, I use either Python, or what's built into Firefox (e.g. unit conversion), or DDG. For that last 1% (e.g. full CAS functionality), I tend to grab whatever web-based non-AI tool is handy.
Interesting that this doesn't seem to include a computer algebra system like the Nspire CAS. Wonder if it's a testing environment compliance thing?

I don't see it. I compared a screenshot of one of these to a older T-84, and it looks like they have same number of buttons, and the buttons are just as cluttered (except the EVO has secondary labels on the keycaps instead of the case).
That's a good thing, since one of the best things about calculators is they typically have a ton of buttons for quick access to a lot of functions.

For a $10 BoM and maybe a year of R&D I would say that $160 is bad.
A TI-83 was about $100 in the year 2000, and it doesn't look like it's that much cheaper today. I would've expected Texas Instruments to try gouging their very captive market.
TI has always gouged their captive market. It is just increasingly ridiculous when those students also have smartphones.
FWIW I think these graphing calculators are quite good for 2026 students! It is nice to have a computer which is actually comprehensible. They just need to be more like $50. $160 is just evil.

Advanced calculators are in an unusual space with external constraints on it. Some of the features or differentiation they add serves the constraint of "if you don't, we won't let students use it in the classroom". When a calculator is used in a classroom, there's a concern about people using the calculator to replace the skill that's being taught. So, for instance, there's space for a calculator with no CAS, for a c…
