[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]TI-84 is essentially a thirty year old technology $9 calculator, but due to TI monopoly, students everywhere are required to buy it and pay ten times, with the $100 price. A $0.99 app on any smart phone incorporates all that functionality and much more, without any ads.
  
But now, almost all standardized tests from college board, digital math courseware,  and schools/colleges are gradually adopting Desmos, so TI, Casio, etc, days in student market are numbered.

People are not trying to save $10 bucks here. They are looking for a calculator suggestion, which should weigh some consideration on features, what’s used in class and available documentation on how to use it.

TI brand is very popular because it’s the default for many high schools and there are a bazillion tutorial videos on the internet.

I don’t know anyone using Casio calculators.[/quote]
People? rich people may not see the difference between $10 and $100, but many others do.  Nearly every AP exam now allows and provides online access to Desmos within the digital test.  Sorry, TI graphing calculators are headed to the grave.

"Desmos has been cutting into Texas Instruments' (TI) business, especially in the educational graphing calculator market. While TI has historically held a near-monopoly due to long-standing relationships with schools and standardized testing organizations, Desmos' free, web-based tools offer a more modern, accessible, and often more powerful alternative"

So what do you propose the OP does, wait for the graphing calculators to become obsolete, or worse buy a Casio lol?

Calculators are tools, use the ones that are the most helpful. You want to rely on Desmos alone at the AP exam? Go for it but it’s quite dumb when there are calculators out here that will make life much easier. Whatever career, people will use technology too, unlikely they’ll do integrals by hand.

Want to save $10, skip the potato chips at lunch, or just borrow the TI from the school library. [/quote]
there are many families who can use $10 for bread and milk. It is ridiculous to tell their student to buy a $100 TI calculator just to get through a public school calculus class, all because TI marketing has succeeded in having the lesson plans and teacher training to be built around their product.  [/quote]

Do you also object to buying your kid books because “milk and bread”? Sure, it’s expensive for what you get, but you can figure that out between buying used, checking one from the school library, or sharing with a friend.

Watch “Hillbilly Elegy” movie, grandma bought a graphing calculator and still had money for cigarettes, and we’re talking abject poverty. I’m sure you can find a way to make it work.

Why are you so worked up about graphing calculators? Just because somebody said your suggestion to rely exclusively on Desmos for the AP exam is dumb, which it is, it doesn’t mean graphing calculators are evil. [/quote]
