If you are studying Algebra or Calculus, I suggest you get a non-CAS calculator for your homework and for use during quizzes and tests, but if you want a fuller understanding of the material, use the CX CAS for additional study in your subjects.
My main calculator for doing homework is my TI 84 Plus CE graphing calculator, but there are other good choices. Using it forces you to learn the material better.
The CX CAS model allows you to cheat, which is why I recommend you only use it for double-checking your work after you do it.
Battery life is actually better than I expected coming from a TI-84 running on AAA batteries that lasted a few months at a time.
There are a few limitations on this that should be noted. It is not possible to work in the S-domain or Z-domain. Laplace and inverse Laplace transforms as well as Z-transforms cannot be done natively. Using the definition of each will obtain a somewhat close answer but as the unit step function is not a recognized function, hand solving for these types of problems will yield the correct result faster than attempting to use the calculator.
An annoying software issue is that it is slow to change settings for a specific document/scratchpad that is open. Changing from degrees to radians or floating to fixed decimals takes around seven or eight button presses. Hopefully Texas Instruments will fix these shortcomings, but I do not foresee any substantial updates within the lifespan of this model.
In short, buy this if you are allowed to use it and need a capable calculator. It does the job even if it takes a little while to input certain types of problems. I don't think there is a better option available on the market at this time.
After getting the calculator, I found I was picking up things faster. I was not using the calculator for everything, but found that going from the problem to the answer I was able to understand the concept faster and with fewer steps of repetition.
I do like the screen, my wife had a TI-85 and it was hard to see even with adjusting the contrast/brightness. This one is bright and crisp in all light.
This one has a rechargeable battery, and after 5 weeks of class, is still well over 90%.
This has a lot of functions, which I have not even gotten halfway into yet. It is great!!!! On my final exam, felt like I was almost cheating.
