Fernando Sánchez: Compre esta calculadora por que pensé que vendría con una funda pero no es asi, solo me llego la calculadora y por lo visto abierta

Daniel Altamirano: Es la versión con CAS. Completamente recomendable comprar esta ya que es un poquito más cara, pero tiene muchas y mejores funciones que la convencional. Está puede resolver integrales indeterminadas.

MilosV: This is a really fine piece of technology and I'm glad I live in a time when it is easily available to everyone, even though it is somewhat expensive; however I think the price is justified when you consider what this calculator can do.
First off I would highly recommend purchasing the Guerrilla Screen Protector . Many other reviewers mention their screen getting scratches or smudges -- the screen protector will make that a non-issue for you. Another thing, the slide cover that comes with the calculator should be sufficient to keep it from being damaged.
Regarding the functionality and capabilities of this calculator...wow was my first response. This calculator is well suited for high school as well as university students. Even instructors could use some of its features to demonstrate certain mathematics to the students as the calculator can be connected to a computer and from there a projector may be used.
The rechargeable battery is really very awesome imo. You will get many hours of use before you have to re-charge the battery and even when you do it is quick -- the calculator is also smart about conserving energy and it will dim the screen and then...

Maxim: I have had this calculator for a week so I cannot speak for quality and longevity, but the UI is very well designed and I figured out how to use it within an hour of playing with it. Although it is easy to use, since many functions are hidden away in menus, it required a few clicks more than my old TI 84 to find certain functions. I also find that this can answer literally any problem I punch into it, nearly everything from arithmetic, algebra, even some calculus stuff like limits, derivatives, and definite integrals (not sure if I can do indefinite integrals yet though)
Pros:
Insanely advanced functionality, with the ability to simplify, factor, find GCF, LCM, and remainder, distribute (called expand on the calc), find zero's, simplify fractions, solve for X, find derivatives, derivative at a point, definite integrals, and probably so much more that I have not explored yet! Much of this is thanks to the CAS built in.
Maybe one of the coolest features is the ability to have spreadsheets and documents on it, allowing one to store important formulas and equations.
It also graphed functions relatively quickly, although the 'drag' with touchpad is painfully...
