CAS can also be used for symbolic differentiation and integration and even for solving symbolic differential equations.
Yoshi Ex
I've used this calculator for mostly all my classes and it works great, a lot of features and still learning new things on it each time I use it.
Greg Uberti
It did and so much more, I would recommend this product to any high school student or college student taking a high level math class.

I got this calculator after having a TI-89 for several years.

What's good about the Nspire CX CAS compared to the '89? Quite a bit:
1. The screen. It's very bright and has 10 brightness levels. Even outside it's readable, just not very well. The screen is high gloss which may prove a challenge in some areas. It does have color distortion at large angles to the screen, but I've yet to notice this in actual use.
2. Some forms of input are much improved. Creating matrices is far less tedious. I also no longer need to remember the order in which to put values for summations and other similar functions. Functions that do not have a math print version and aren't self explanatory often have wizards to guide you through their use.
3. It's faster, substantially so. Complex graphs are no longer glacial. Very large numbers and functions no longer lock up the interface for seconds at a time.
4. The catalog is organized either by subject or alphabetical. When sorted by subject, instead of listing them as comDenom(, arccoth(, etc. They're listed as Common Denominator and Inverse Hyperbolic Cotangent.
5. The calculator is thinner and the rubber feet have better grip.

There are also some disadvantages:
1. The pipe key is way more out of the way. It's hidden behind 6 keypresses. This is countered by the ease in which functions can be defined, but that is only really faster than the old method if you're doing functions with more than 2 variables.
2. The touchpad is touchy. I've had it suddenly go into touchpad mode when I was pressing the arrow keys and the movement is slow and jumpy. However, nearly nothing requires the touchpad's use.
3. The majority of the math buttons are on rocker keys.

This is one of the first graphing calculators, just behind Casio, that provides a color display.

So what is great about this calculator?
1. Templates, templates, templates! Have a hard time understanding how to solve an integral or a system of equations on your TI-89? The TI-Nspire Cx CAS has easy to understand templates for solving integrals. In other words, this calculator will set up an integral just the way you would see it in your book, simply tab or arrow over to an empty box and fill it in.
2. CAS (computer algebra system) This helps solve for variables and can help simplify expressions that the non-CAS calculators couldn't hope to do. For just 10 or 20 dollars more for this feature (it is included in this calculator!), it adds a whole new level of functionality to your calculator, and the non-CAS calculators will tease you about these functions, but will tell you that CAS is needed in order to perform them. Also, This calculator looks more professional than the standard CX calculator, at least in my mind.

So what is good about this calculator?
1. The screen provides a clear display, of course, the display could be improved on, but it really doesn't seem that necessary. Another difference is that the screen is in line with the rest of the calculator (the screen is not indented into the calculator as it is with most other models), providing little protection against accidental drops.
2. The sleek design. It looks much more professional than the older Nspire models and is much more sleek, but it provides a little worry when it comes to strength and durability, but you would have to be rather careless in order to break it.

So what is slightly annoying about this calculator?
1. The Li-Ion battery.

I am a high school student and purchased this calculator mostly for my calc 3 class I take at a nearby college. I had to decide between the ti-89 and this one and ultimately decided on the cx cas. My friends all own ti-89s and the key difference I saw between the two calculators was the use of templates. The ti-89 maybe much more familiar for many people but for me, the math templates makes things easier to integrate, differentiate, etc. Also the screen is quite beautiful but can be scratched easily. The screen is clear and vivid. The calculator is also extremely slim and looks amazing. Whenever I take this thing out, everyone always swarm over to admire its beauty. It always attracts attention. The battery life amazed me. It lasted longer than what Texas instruments said it would. I use this calculator very often and the battery was at 50% after 3 weeks of use. I am very happy with my purchase.

Pros:
Templates are extremely helpful
Battery life is amazing
Expect people to compliment you (until this thing becomes more common.)
Screen is clear and vibrant
Looks and feels amazing
Super thin
Nice change from the typical ti-89

Cons:
Screen scratches easily
Some people may "borrow" your calculator longer than you wish
Getting locked in test mode could happen quite easily and has happened to me already. (just find someone with any ti-nspire and connect the two calculators then open up the document called test mode to unlock)
Screen is a fingerprint magnet
Some may still prefer the familiarity if the 89

Hope this review helped!
