You're not going to regret it. But I would do more shopping instead of just running with Reddit's advice. Sure the CX CAS is more than you need most of the time, but did you know it's not the fastest CAS calculator on the market? HP actually makes the fastest one. Also Casio makes a very user friendly touchscreen calculator that even comes with stylus. How cool is that?

But like I said, the CX CAS is basically all you need. I just hate seeing these calculators get left out all the time.

>I believe that the government should require that all publically funded schools accept all graphing calculators regardless of who produces them or what brand they are and instead bases them off of functions necessary to complete the curriculum.

Already you can use any graphing calculator. Incidentally, there are numerous calculator companies in business. Do you mean for the government to impose penalties on schools that recommend a specific graphing calculator to complete the course? What kind of law do you want to make and what would it say?

Aside: there are legitimate reasons to ban graphing calculators that are too good in classrooms. If there is a test on integration, having a calculator that can show you step-by-step symbolic solutions can invalidate that test. You can argue that being able to integrate by hand is a stupid skill that's not worth learning, but that's a very separate argument.

See more SAT rules for calculators here. Both for a stunningly long list of competitive graphing calculators and for some features that are banned in some testing situations.

>So, for starters because of the textbook industry the use of the TI-83/84 has run rampant and has monopolistic competition on college campuses (and thus relevant work places) as a result.

So? It's tried and true. I work in finance, and we all all use Dixon Ticonderoga pencils because they work. Oh, and we all have HP-12cs, lol. Would you propose a law banning Dixon Ticonderoga because their lead is too smooth, and their grip is so light, and their eraser too supple? "Your product is too good! Destroy it and design it again!"

>This monopolistic competition allows them to charge up to $150 for a Calculator that has not been improved upon since 1996.

So? Lots of things aren't cheaper than they used to be.

>Today most phones (even non smartphones) are more powerful than both of these calculators in terms of raw hardware.

I hate responding to every single one of your points with "So?" but really: "So?"

What, specifically, do you want a graphing calculator to do that it can't do? Keep in mind also that there are way better graphing calculators out there, just nobody buys them because the purpose of a graphing calculator is to help students learn math skills more than it is actually used to solve problems.

I can't honestly think of a single function I want on my TI-84 (as a learning/educational tool) that it doesn't have. It would be nice if it were faster, I guess, but it doesn't make sense for them to redesign an entire calculator just to make it as fast as your dumb phone.

It does everything that you want it to do.
