Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator with Student Software (PC/Mac)

Cons: - Screen is painful to look at; poor anti-aliasing and blurring issues. - A touchpad that makes selecting anything a PITA without accidentally changing the selection. - An enter key that is awkwardly located far from the touchpad. - Math keys are fused into franken-buttons (one key with a dead-space between the sides). - Very poor tactile confirmation that a key is even being pressed. - Cheap Playschool plastic case. - Glued-on rubber anti-slip feet likely to fall off with any regular use. - Not as light as expected despite being thinner. - Trig functions and commonly used constants are found in menus rather than broken out into separate buttons. Inexcusable design choice. - Alphabet keys are, astoundingly, not in standard keyboard order despite being arranged like one. Everyone has a smart phone, why would you not copy that layout? - Despite the beefy processor specs, everything feels sluggish. Noticeable input lag. Pros: - If the screen werent so terrible, the operating system would look good. - Full fledged file handler and tab manager is pleasingly modern. - Its a python interpreter and advanced math engine in a calculator. Thats amazing. Final thought: - TI needs to fire their hardware people for designing that franken-button layout. If the four math keys most used feel like hot garbage, thats a pretty big issue. - The anti-aliasing needs serious reprogramming. No functionality can make up for a screen that causes immediate eye-strain. - Replace the touch-pad with a d-pad. Youd improve the interface and save a couple bucks per unit at the same time.

This calculator will help you cheat or check your work. Unlike older calculators you can put the problems in just as they appear in written form. Downside is you dont learn anything besides operating calculator.

Expensive but worth the investment. You can find it cheaper elsewhere but if you want the peace of mind that it will be perfectly new buy it on amazon. The added Computer-Algebra-System isn’t something most people need but it’s worth the extra money as it makes problem solving very easy. It comes with a code to download an emulator on your computer. I use that to right notes on my computer and download them straight to the calculator (very easy to do). It takes some time to get used to the way you use it. It’s more like using a computer but you will get used to it. If you plan on doing anything STEM related this is a great calculator to have. You can download software for almost any subject from algebra to A high level Differential Equations class. If you want to save a little money the previous color model is almost identical aside from color (at least in my experience).

Es un excelente producto para aquellos estudiantes que pueden usarla como herramienta. La recomiendo para ingeniería y ciencias exactas.

The learning curve is a bit steep if you are not familiar with TI calculators but the payoff is worth the effort. It does most everything you might want to do in mathematics. From algebra to xyz plots the TI-Nspire CX II CAS color graphing calculator will do the job. It is light weight and the keys are easily accessible to larger fingers. The screen is a good size too and easy to read. However, it would be helpful for older eyes if you could enlarge the mathematical text. You can enlarge the document text. I graduated from the TI-84 Plus, and I am not at all disappointed, in fact, very happy I did.

Took a while to learn the interface and all the features, but it is a great calculator and saved my life in calc. The notes feature is very helpful and the quality is great!

I’m a senior citizen who received a large portion of my education before calculators were invented. It was all slide rules and tables of logarithms. This device is utterly amazing. Texas Instruments in Australia have produced many useful YouTube videos that collectively demonstrate everything the calculator does. It will take a lot of practice to become proficient but that’s the fun part.

Great product and worth the money

Got this for my son who needed it for high school and college calculus classes. Many schools provide these as loaners for students as well.

I was a loyal HP-fan for 34 years, starting with the HP28s back in college. As an electrical engineer, I progressed through several upgrades up to the HP50g. Then I got the HP Prime, and at first I hated it, so ignored it for almost a year. But then it grew on me, and I kicked myself for not adapting to change sooner. But, there was always something annoying about the Prime, where for every convenience, there were almost two inconveniences. Then I decided to try the TI CX II CAS Student Software trial for 30 days, and I was blown away so I bought the calculator from Amazon! Why, oh why, did I torture myself with HP for so long?!?! Nearly everything about the TI is easier, and despite looking student-centric (which could be interpreted by some as a toy), I promise that this will be your work calculator. The document-based interface is exactly what I needed - I rewrote my HP applications for TI, including a few new ones, in a fraction of the time (the language is easier, the editor more intuitive, and the dedicated keyboard destroys HPs multi-click, illegible color scheme, keyboard). I wont bother looking at HP anymore - Im sticking with TI. There is no way to describe the experience with this calculator here - just buy it and if you dont like it, return it (but you wont!).
