5 out of 5 eggsThe Cx CAS is a must have

Pros: This calculator has so many functions it makes my head spin. It can deal with polynomials and radicals (2 things I cant deal with.

The CAS can manipulate multiple varibles in an equation and has a full keyboard so you can use whatever letter for a variable your heart desires. I am about to get an A in a class I was coming close to failing

Cons: none- but make sure you dont get the non-CAS or else you just shot yourself in the foot

easy to become dependent on CAS for answers- but who really cares as long as your professor allows you to use it on tests and you have a non math oriented major

Other Thoughts: I upgraded to this from a TI84+C silver and the TI Nspire CX CAS calculator is leaps and bounds beyond it. This calculator will do all your work for you, and im not exaggerating. This is an amazing product and you will be satisfied, especially if you struggle with math as I do.

5 out of 5 eggsOne of the best tools I have.

Pros: - Got me through physics 1 like a breeze
- Backlit screen
- LONG battery life
- Included software is good
- Pretty intuitive
- Can use Lua on it natively (and C++ if you work at it)
- Trackpad is easy to use
- Easy to work on more than one thing at a time
- Has a mouse pointer
- The user-definded functions work amazing

Cons: - The software is only licensed for one computer
- You have to work at the touchpad a bit to wake it up
- The 100 MB storage memory is low in my opinion. (At the end of the day its the only thing I feel limiting it.)

Other Thoughts: I love this thing, I use it at least every other day.

4 out of 5 eggsGood Choice For Engineering Major

Pros: As an electrical engineering student, I needed an advanced calculator to handle the large matrices, linear equation solving, symbolic equation manipulation, 3D graphing and ect. This calculator fulfills all of these requirements and more besides. The screen is bigger than the standard ti-84 and even the more expensive ti-89. Although the ti-89 is regarded as one of the defacto engineering calculator, I feel that the Nspire can do about as much as the 89 (and perhaps even more). The usb rechargeable battery is a big plus, and the charge so far has lasted about 2-3 weeks of moderate to heavy use (although this time will probably decrease slightly as the battery ages). I also greatly appreciate the computer inspired drop down menu system of the calculator's functions. Functions are given full names (no more bewildering calculator code names), and the most commonly used ones frequently have a mini program that walks you through the function setup. The graphical arrangement of many functions like integrals and matrices make them look exactly like they do when you write them out. This greatly improves my understanding of how to use the function without having to refer to a manual for syntax. I literally learned more about how to use this calculator in a week than I did with my previous Ti-92 in a year.

Cons: Due to the more intuitive menue system utilized by the Ti-Nspire, it probably takes slightly longer to enter and use functions than on a standard calculator like the 89. However, I would gladly trade a slight loss in speed for improved usability and therefore reduction in error. Also, it takes more keystrokes to enter certain common functions (most notably the trig functions which have their own menu key). Nevertheless, the time difference is not intolerable. The keyboard is also not qwerty, but I believe this is a necessity for the calculator's acceptance on certain tests.

Other Thoughts: This calculator is certainly more expensive than the 84 (although surprisingly, cheaper than the mostly un-updated 89), so if you do not intend to do complex systems of equations or large matrices, I would suggest buying a cheaper model. It is possible to use an 84 (and many people do) for most upper level classes (statics, circuit analysis, ect) but if an occupation requiring such advanced classes is your intended or current field, I would recommend buying such an advanced calculator as it can greatly improve your problem solving ability. For example, I don't think (but don't quote me on this) that the 84 has the ability to solve a system of multiple equations for multiple unknowns (very useful in certain statics and circuit analysis problems).

5 out of 5 eggsHuge Upgrade

Pros: - Color screen makes it easy to tell the difference between multiple functions on the Graph screen.
- CAS makes it very easy to do many algebraic tasks quickly. I'm a Comp Sci major minoring in Mathematics and I'm already seeing huge improvements in the time it takes me to solve problems.
- Built in unit conversion and ability to easily define new units. On my TI-84, this required a separate program and if I wanted the ability to expand my unit selection I had to write my own program.
- Can build programs using LUA in addition to the classic TI-BASIC.
- Can calculate derivatives, indefinite integrals, and limits.
- Dedicated alphanumeric keys makes entering many variables, labels, and text much easier.
- Best support software of any TI calculator series. Combines programming IDE, file management, and emulation all into one single high quality application. You can even try all the features for 30-days before you buy! This was a huge factor in my purchasing decision.
- Rechargeable battery.

Cons: - The CAS functionality disqualifies this model from use on the ACT (it's still allowed on the SAT though). This was a non-issue for me, but it may be too big a drawback for others.
- Not all instructors allow models with CAS. Some do, some don't. I recommend having a TI-84 as backup for those instances. This is the primary con that kept me from buying a TI-89 when I got my first graphing calculator years ago.

Other Thoughts: I am upgrading to this from a TI-84+ and I am very happy with the switch so far. I especially like being able to type up short sets of notes (ideal for must-have equations) on the PC.

5 out of 5 eggsBest Calculator Out There!

Pros: This was my very first graphing calculator I ever bought/used and I couldn't be happier! I'm a college student and needed a graphing calculator for precalculus and I am so happy I bought this one and not any of the others like the ti-83/84. It is very powerful.

Cons: Not really a con but it does take some time to learn all the functions.

Other Thoughts: Wish I had this thing when I took algebra, would have made my life so much easier. I had it for couple months and I'm still learning new things on it.

5 out of 5 eggsGreat Investment

Pros: Great Display.
Student software that comes with the calculator is pretty awesome.

Cons: Not huge on the keyboard, it's alphabetical like other TI calculators. Would prefer a QWERTY, but other than that, it's a great calculator.

5 out of 5 eggsgreat device

Pros: A HUGE improvement over the Ti-89 titanium. A color screen, friendly computer interface and including physical constants WITH units is great!

Cons: pointer/mouse a little troublesome to start using but when it knows you want this feature it works great.

Other Thoughts: I used the Ti-89 titanium for an undergraduate chemistry/math/physics degree. I was then admitted to a doctoral theoretic chemistry program and have found this calculator an invaluable tool.

Solving for variables in complicated expressions and expanding tedious expressions has become a breeze and I cannot understand why Texas instruments is not charging more for this device.

5 out of 5 eggsGreatest Calculator Ever

Pros: Just Finished up my Calculus 1 class and this calculator was great. It can nearly do everything. Its color screen makes it great and you can read graphs very well with color. Its just a great calc. get it if your going high into math classes.

Cons: Sometimes a little to powerful, you can pass a test and not know how to actually do the material.

Other Thoughts: Great :)
