Is the era of the $100+ graphing calculator coming to an end? [thehustle.co]
Porting isn't really that big of a problem, and the math operations that thing does are so simple I'm not even sure if there's need to optimize anything unless they use totally outdated processors from like the 80s.
Sounds to me more about everything else (monopoly, behind the scene stuff, etc) than technological reasons to me.

Heck, I even have a Casio fx-CG500 [amazon.com] but that's mostly to keep my oldest entertained with things like the integral period table of elements on short road trips. Despite my affection for it, someone on this thread more familiar with actually using it as a calculator will have to convince me that this beast is somehow going to beat my TI-Nspire at linear algebra with any speed(?).
Good luck!

It's still the same *extremely well-known* z80 "architecture". The bulk of development/optimization cost are already paid years ago with extensive amount of know-how's, and jumping to the later processors in the family doesn't mean you're scrapping everything and re-develop and re-optimize stuff. That's exactly why they simply chose a faster z80 to *minimize* the work to reinvent stuff. It's not some quantum jump as you think. Outside of that it's still some pitiful cheap amount of RAM so these things are dirt cheap to manufacture (and thus REAL reason to optimize it, because the hardware is just pathetic).
And if you think the math this thing does is "complex" by today's standard...you're on some really serious drugs.
You also don't understand how fast processor architectures change.
You also don't recognize that TI has been releasing new calcs every 5 years for the past 20 years.
News flash, you full color TI calc of today is not based upon the 68000 processor that was used 20 years ago.
No, I'm talking the TI-8x, not those new Nspire ones. TI milked enough money on those Ti-8x over the years already.
Do you know more people worldwide use Casio's? Sorry to burst your bubble, TI calculators aren't the greatest thing as you think.
So stop complaining about what the market is willing to bear and that they have had a successful business model for 20 years. You are just silly.
In any case, you refuted my argument with zero additional information other than saying "no I don't think so from my armchair expert location"
But, yes, go with the monopoly evil corporation theory OR, go get a raspberry pi, add an LCD, put python on it, make it work on batteries and compete at 1/4 the cost....
To give you some ideas, a 640x480 LCD for Pi Zero can be have for about $25, and Pi Zero (which the CPU is obviously on a different level than z80) itself is $5 retail.
It uses the eZ80 processor from Zilog, making all Z80 assembly programs from the previous TI 84 Plus series calculators incompatible

Like I said. Let's go with calculator monopoly as a reason for the prices because that's cooler and doesn't require facts to defend.
It's well known fact they are incredibly similar and people have little problems porting from z80 to ez80.

Lol, then you edit your post to try and sound like you knew what you were talking about in the first place.
Some people are always going to be salty at paying for changes they can't see. But if things hold their value who cares? Buy it for $100 and sell it for $90 after the semester, like most of us did. You benefit just as much from it holding it's value over time. In 2000, $10 to rent a machine that helps you pass AP exams AND play tetris seemed like a pretty solid deal to me.

So they want to make money on their intellectual property? You can do better for $10? Go for it. They also have no competition except HP and Casio, and traditionally TI's user experience has been MUCH better. That's why it's so widely adopted.
