5.0 out of 5 stars Superb calculator
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...

3.0 out of 5 stars Screen Protector Please!
Brought this as a replacement to my TI-84 - Overall it is good but the screen scratches easily and is subject to glare - Would help if I could buy a screen protector but none appears to be available for this product

4.0 out of 5 stars Best portable calculator, but..., 2 Feb 2014
This review is from: Texas Instruments Nspire CX-CAS Graphic Calculator with Touchpad (Office Product)
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, the calculator charges incredibly slowly (even when connected to wall adapter), and the cable has to be inserted in a particular angle in order to charge.

Besides that, the menus are not extremely intuitive, but it gets the job done, with hundreds of functions coming from various types of math. If you're at school, this is an absolute must, assuming your school allows this calculator.

If you need a portable calculator, this is the one to have. But if you don't need a portable one, check out wolframalpha.com

5.0 out of 5 stars This is the Best Calc out there!, 20 Jan 2012
This review is from: Texas Instruments Nspire CX-CAS Graphic Calculator with Touchpad (Office Product)
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.

Yours
Computer Science+Economics Major,
