Texas instruments have dominated the high-end calculator market in recents times. Their functionality is unrivalled. However compared to other modern handheld technology their greyscale displays and reliance on replacement batteries have meant they looked like they were stuck in the stone age. All this has changed with the introduction of the CX series. I bought a CAS version direct from Oxford Educational Supplies and it has immediately made my other Texas Nspire calculator redundant. Now I can see all my work displayed clearly - no more squinting. OK the display is not as good as an iphone, but compared to what I owned before, it's a quantum leap. The calculator isn't that bulky either and the battery life is excellent.

Okay, you've probably read other reviews on how this calculator is the best portable one out there and all... And I agree. So if you need one, buy this one.Even though it's the best one out there, I have encountered some problems.First of all, the case seems to scratch the screen quite a bit. And it's not only on my calculator. I have lines on the plastic screen that diffract the colours.Second, the battery indicator tends to work fine when it's at 50-100%, but when it goes under, the battery life just seems to diminish faster. I did calibrate the battery by emptying and charging up to 100%, but it didn't really change anything.Thirdly, when charging by mini-USB,

Sometimes it surprises me by its cleverness; sometimes I am frustrated by its dumbness. Good but could be better is my overall view: it's not as good for example as the free mathematical tools available on the internet at Wolfram Alpha.However - it is a calculator and does have the advantage of quick access and portability, so on the whole I'm glad I bought it.A point I discovered later - it's integration routines are not completely reliable. One specific straightforward example (easy to describe in text format) is :-Definite Integral of sin(x) / (a - sin(x)) between -pi and pi.The answer on the calculator is -2pi which is obviously wrong as the result has to depend on aTexas have admitted the problem (a year ago)

This calculator is great as an example you can take pictures and transfer it via PC USB link and analyse various aspects of the picture eg the hyperbola of an archway. When working on a problem it starts its life as a document you then can add functions, graphs, datasets etc to the document. The 100MB of memory is shared with the OS thus filling the library with how-to's etc will and does slow it down big time so once you learn how to then get rid of so not to fill up with crap and the calculator performs great. Real sensors can be connected and read by the Vernier Dataquest (tm) app. Great tool for all budding Engineers

Hello,I recently purchased a TI NSPIRE CX - CAS calc. The CAS is a much more awesomer calc than the non CAS version 'cause of its Computer Algaebra System which'd allow you to get answers like in your textbook ( atleast in mine ). It's a great calc to both do any math, ANY is not understated and put down a solid impression at any class/lecture. I have no words to speak about the calc's mathematical abilities. It sure is THE BEST. Way better than Ti89, Voyager, Casio PRIZM etc etc.YoursComputer Science+Economics Major,

I can recommend everyone to buy the CAS variant of this calculator. If you need adavanced mathematics, integrals differential equations, series expansions, graphs, statistics,... the TI-Spire with CAS is what you need. The touchpad comes in handy, but not always as practical as it could be. The (online) manuals however, don't provide a tutorial or an usefull help. Even the calculator is easy to use, using the advanced functions and their interaction has a steep learning curve. So I am considering buying

I bought it for my son, He was using it for maths for O level and APs. He said Texas N3CAS/TBL/2E7 TI-Nspire CX CAS Graph Calculator is the best and was more then enough for his level. To him it was very useful for him. it was also recommend by his math teachers. He scored A* in both of these exams. He also told it has good visibility/readability. Battery life was also satisfying.

Update (Mar 2018): I finished university, with this calculator at my side. Every bit as capable and reliable as I imagined. Highly recommended!Original review (Feb 2015): If you think you could benefit from this calculator, you're thinking too hard. Extremely capable and powerful, does everything I could need it to do and more. Looking forward to using this through university!

It has all the features you need for practicing and using during university. The interface and UI can be a bit tricky to get around. The software that is included that you use to install a virtual version of it on your PC is the deal breaker when buying this, it is so handy and easier to use than the device itself.

Very nice, but please be sure that you actually NEED something like this. I'm an engineering student and I found that it sits in the draw a lot. Bit of a luxury toy that i forgot about quickly rather than a need.Cons: Price. Keybord layout has you stretching, illogical layout for some frequently used buttons.

Brought this for my Son as he is currently studying Futher Maths and had been pressured into buying it by his lecturers.He seems happy with it, does as it says on the tin and ideal for those studying Maths at A or Further Maths A Level and higher.

I have been buying programming and graphic calculators for years (the first one was Sharp PC-1246). This one is the best so far. There are two negatives of this calculator: battery life (few days top) and boot time (cca 1 min.).

This is not a simple calculator and is difficult to use, the manual is difficult to read, and is not intuitive. The CAS version is of limited use for an average person.

This is the first graphical calculator that I've bought and it meets my expectations and it can do almost everything especially in Math and Physics.

As usual TI is excellent it is my second one, I gave one to my younger brother doing engineering
