  • Outstanding
So the time has come to send my oldest to middle school. His school requires the use of one of two calculators in his math class...the TI-84 Plus OR the TI-Nspire. After doing a LOT of research I settled on the Nspire. Why? Well.... At first glance the TI-84 would have been the better choice. It's based on a platform that was first introduced in 1996, and twenty years later the market has had a lot of time to embrace this calculator. Indeed, there's a vast amount of resources out there to support the TI-84 and having all of that would seem to make the case that it is the best choice. The lower price point is also another factor. But then my research started showing something. The updates for the TI-84 had been doing a commendable job at beating back the clock, but the reality is the hardware is aged and can only do so much. While it may have been the best calculator in the world ten years ago, the reality is that was ten years ago. In other words, it is now limited and will always be limiting going forward. Add to that TI's loving attention to the Nspire, and it becomes clear that the Nspire is the new platform. Equipping my son with yesteryear's technology would be, I think, to put him at a disadvantage with his peers. So the Nspire it is. Sadly the school outright prohibited the use of CAS calculators in their list. More's the pity, as the CAS version offers some very compelling features and abilities at a trivial price increase. If it weren't forbidden, my son would have received the CAS version of this calculator. On the other hand, this particular model will serve him well into college, so buying this platform today means I don't have to buy it for him in six+ years. And if the need for CAS becomes acute then, well, the CX CAS will be waiting. Using this handheld (it's really not a calculator, but a mini computer) has addressed a lot of the nonintuitive quirks of the TI-84. You work with documents, you can interact with things directly via the touchpad, and so on. Regular OS updates ensure that this platform has a LOT of life in it. Too, the Nspire has capabilities that are simply impossible for the TI-84 to have, like 3D graphing. On the other hand, since math teachers tend to be a staid and Victorian lot, you'll still see the TI-84 hanging around schools longer than I think is wise. Since TI stopped selling the TI-84 keyboard attachment for the Nspire, it's clear that TI is committed to forcing the issue. Better to, I think, learn the platform of the here and now vs the old one. What put me over the edge was a brief survey I took of the engineers in my office. To a man (and woman), they agreed that the Nspire was the way to go. So that's why I bought this, and the support from TI in addition to the software tools (the PC application, document transferability, etc) has made that decision a wise one. I firmly believe this is the best, most flexible handheld calculator device on the market today. I armed my son with this, a couple of tutorial books, and let him play...and he's taken to it quite well. It's an outstanding device. ... show more

  • Excellent for any math or science course (AP courses and most college courses as well)
This is an excellent device, and although it takes getting used to, it is much more intuitive than the TI-84 and others like it. While other calculators offered by TI also have color LCD panels, this one seems to match the aptitude of this calculator, finally putting all the power and functionality under the hood. It offers plenty of space for documents and pictures, which can be helpful in graphs and determining geometry. It doesn't stop there, though. I'm a high school sophomore in Precalculus and AP Statistics, and this is more than enough to get me through these classes, because it offers a much more computer-like intuitive workspace rather than the often obscured environment on the TI-84. I find it handy to be able to type in my operators, especially in Precalc, because experience with this has let me type much quicker. If you have never used one of these, I found it handy to have a "study buddy" who knows or is learning how to use this. I would also recommend finding a "scavenger hunt" like activity from TI's website to learn the basics of what your calculator can do. Then, experiment with it in your free time. Create a new document and play with the various functions. The great thing is, if you mess something up, you can just delete the page or even the entire document. Many of the key combinations that work on PCs also work on the TI Nspire, like Ctrl+C for copy, Ctrl+V for paste, Ctrl+I for new page and Ctrl+S for save, which helps the learning curve. ... show more

  • Score one for Dad!
I bought this calculator for my daughter who is in ninth grade. Ninth grade! I was a bit shocked when I heard the graphing calculator requirements so early. Maybe that's a good thing, I thought. Maybe she'll be cranking out high-level mathematical graphilicious graphs of doom. With the power of this TI Nspire CX Graphing Calculator in her hands, my daughter could one day rule the world. Okay, that's not really how it went down. In truth, I was miffed. I just spent a few hundred dollars in school fees and now I was being asked to purchase an expensive calculator for a class I was sure wouldn't be using it to the full potential. At best, I figured maybe some brainiac would show the other kids in the class how they could script little games and build funny functions of prepubescent bliss. I guess tech familiarization under the guise of math isn't the worst thing we've got going for us, so I bought in. I pulled up Amazon and started pricing the requested models. The TI-Nspire CX was at the top of the range, but I found a used one for a killer deal. The description indicated the device had only been used one semester by a college student and the pictures looked good. A swift discount and a click to buy later and we were both happy campers! My daughter got props from the teachers for showing up with such a nice calculator with its fancy color screen. And I got the cool dad points for getting a kick butt calc for the price of the standard lower end comparables. I love you, Amazon. ... show more

  • Great buy! Just like seller said, works perfect for college!
I found this TI-Nspire CX calculator on Amazon for only $49 used! It was just like the seller described, even with the charger! You can tell it's been used (some small marks on the back and cover), but it works perfectly! I just had to charge it once, and now it lasts really long. The battery is great! The colorful graphing feature is awesome, too, making it super helpful for my college classes. Overall, I'm super happy with this purchase! It's a powerful and affordable calculator, perfect for students. I highly recommend it! ... show more

  • TI Revamp is spot on
EDIT/UPDATE: If you are taking any math beyond pre-algebra or algebra 1 you will need at a minimum the TI-Nspire CX-CAS and NOT the TI-Nspire CX. The other version is better for algebra 2 and beyond. I typed in the command to extend a ploynomial and the TI-Nspire CX had a pop up that said, "try the TI-Nspire CX-CAS" It's a great calculator all the same, I really wish I had known it was not advanced enough when I bought it about 3 weeks ago. I have my second math exam tomorrow and will have to familiarize myself with the TI-Nspire CX-CAS tonight. Thanks to Amazon's same day shipping it's only a minor set back. Immediately worth it. Many years ago, I was loaned a TI 81/82/83 to use in school. I never bought one. It never occurred to me that a newer version would make that much of a difference. I thought, "I can use my phone for graphing and stuff or a computer program." I never gave much thought to a futuristic TI-Nspire graphing calculator. I had a scientific calculator and was mostly a C student in math, until now. Now I'm in college algebra at Thomas Edison State University and I saw my math score go from the 80% range to the 90%+ range. I became an A student with this calculator. Having the right tools for education make all the difference in the world. I absolutely recommend investing in your future with a good graphing calculator and for college students this is a must have. I was completely floored by the trackpad style cursor button! It was pretty easy to use. I haven't used a graphing calculator in 12-ish years, but I picked this one up and it was familiar enough that I could immediately graph and perform algebraic calculations. It came just in time, despite our Nor-easter storm. I used it today for my first college algebra test, graphing, functions, systems and all that fun stuff. I love that this calculator is the perfect blend of the classic TI calculators with some futuristic feeling features that make it a little more zazzy than the older non-backlit 8 bit pixelated clunky calcuators. This one is light and holds a charge and can work for a long time off a single charge. No more eating batteries the way the old ones did. It's also super light. I was nervous about the purchase at first but it is 100% worth it. ... show more

  • Quality product
Good quality calculator that will last you for years to come. This calculator has lasted me from high school math up until the end of my college year (still works like a champ with no issues, but I just don’t have much of a use for it anymore). I bet it could last another ten years. High quality product and easier to use than some of the other graphing calculators available. ... show more

  • Welcome to Modern Calculating
If you are debating on getting this or another calculator like I was, look no further. Get this. I was originally concerned because the TI-84s are still the standard in classrooms everywhere meaning that all the teachers know how to use them making my life easier. Well, you don't need help if you get this TI-Nspire. Its intuitive to use and makes calculating a lot easier because everything is right where you would expect it to be and is in the format that we are used to using when writing it down on paper. In addition to having significantly more functionality already than the TI-84s, You can install programs that you might find useful such as a Significant Figures Calculator which I use in my Chemistry 181 class regularly. Theres also the wow factor as many people haven't even seen this calculator before. TL,DR: Buy this. Its better than Ti-84s and not all that much more expensive. Its easier to use too. ... show more

  • Intuitive, nice delivery time, but slightly bad packaging
The packaging was a bit deformed, but it is more likely the problem of shipping than the seller. The calculator itself was intuitive and easy to use (if you used a GDC for the first time). For those who are used to TI-84, it may take some time getting used to, but the result is worth it. Graph processing, inputting functions, calculating definite integrates and so on uses 50% less time than the TI-84, and is much easier. The UI clarifies numbers, and the better LED screen really helps me to lessen my mistakes of copying wrong values through the use of a more natural font. SAT, AP and IB all approves this model, along with others. I highly recommend this calculator, because the time you spent typing those chunky expressions (made faster through the mini keyboard) will be saved dramatically, giving you that much-needed extra two or three minutes to finish off that last crazy hard math problem. (Not to mention the ability to "cheat" by using the graph to derive vertices directly from a given function, rather than going through the standard process of algebra) it helps you to kill all those easy questions in seconds. There are several problems though. The 3D modeling component is a bit less intuitive and hard to manipulate, and lacks certain features (though if they allowed, they will be banned from being used in high school level tests) It is hard to delete certain features (as required by IB) In some schools, you may have a hard time learning how to use your calculator if TI-84 is the standard used by teachers. That happened to me, but I was able to catch up within a week, and me being faster than my classmates helped push me to being top in mathematics (seriously, I got 10 more marks than the second SIMPLY because I had more time to do the harder questions because of the calculator) ... show more
