Nice item, escecially when you need it for class

What else can be said, but this is another calculator made by TI that works and is required in the class room.

Completely Illegal, yet lots of fun.

After using this calculator throughout 10th grade Algebra II, I thought I might as well get around to writing a review of this newest TI product.

The Pros:
Elegant and efficient solver screen. This calculator does everything: it solves equations, matrices (in pretty print, no less), factors, solves systems of equations...just about anything you ask it to. I could *almost* use this calculator exclusively in algebra class and sleep through the lectures. The only problem I ever had with it was when I wanted it to "complete the square;" a rather obnoxious process in Algebra that takes forever to do by hand. The prevalent pretty print is nice, and I agree with the reviewer who said that parentheses errors are a thing of the past with this calculator...as well as fractional errors, radical errors, order of operations errors, etc...

The Cons:
Just like most of the other reviews said, terribly documented. Figuring out this calc is a real hit-or-miss, guess-and-check process. I cannot access half of the graphing features on this calc, and I don't even know where to begin when doing stat plots. The ability to run split-screen programs is nice; especially if your problem asks for the XY chart of a graph. However, finding intercepts, linear-or-quadratic regression, stat plot trends, etc, are all pretty much lost in translation, and I don't have the time to figure the features out in the middle of a test. Thus, even though I have the calculator that can do everything, I still need to use my TI-84 at times, which draws jeers from my classmates (as in "Geez, how many calculators do you NEED?!"). Also, this calculator is prohibited on almost all standardized tests, as well as most school tests, due to its ability to solve equations, so it loses value right there. Minor issues include screen contrast and button placement (I have big thumbs, and often times, the side of my finger inadvertently hits those annoying little letter keys). One further problem is that the N-Spire's keyboard features different keystrokes from the scholastic standard TI-84, so you have to adapt to classroom demonstrations on the fly, which can get annoying while trying to take rapid notes.

Overall, I love this completely illegal piece of cutting edge technology, but be forewarned: get your PhD in rocket science first if you want to use all this calculator's features, because you sure will need it. Or else, bring your TI-84 along as backup and endure the jeers of your classmates.
