This is a calculator with tons of potential, however it is not nearly as user friendly as every other TI graphing calculator is. I'm an AP Calculus teacher and ordered one of these through school funds to test out. It can do everything that the TI-89 does and has much more potential than the TI-89, but the thought of teaching my students to use one of these just scares the bejesus out of me.

Pros:
1. Large screen with good resolution.
2. little green letter buttons make it easier to enter commands.
3. WYSIWYG typing means you don't have to remember calculator syntax. It's much easier to enter a definite integral or limit.
4. Graphing window allows you to graph rectangular, polar, and parametric equations simultaneously.
5. Click and drag feature on the graph screen is nice.

Cons:
1. The letter buttons are always in the way while I'm trying to enter numbers.
2. Screen can be difficult to read.
3. There is not a model that hooks up to a TI presenter. It does come with software where you can use a computer version of the calculator (assuming you have an LCD projector), but it's much slower than simply hitting actual buttons.
4. Finding max, min, roots, and intersections takes longer than on the TI-89.
5. When you do find the things from my #4 con, the calculator displays them right in the middle of the graphing screen, so you have to click and drag them out of the way to continue viewing the graph.
6. The "y=" screen is included as part of the graph screen, taking up graphing space.
7. Viewing a function table isn't difficult, but I can't figure out how to view a window containing ONLY the function table. It splits the screen with the graph on the left and the table on the right.

Verified Purchase
I've been working with this calculator for more than two months. My advice? Wait! Wait for updates and upgrades. First, I have to agree with another reviewer who was so angry with the documentation: it's awful. Harks back to the early 1980s when the only way to know what a computer could do was to try it. Trying to figure out how to do even the simplest of operations sometimes required an hour's worth of searching, at times with no resolution. The most helpful thing I've done so far is to print out the entire function manual and read through it page by page, but even this won't help you with specific button operations. Also, if I call technical support and they say they'll have to call me back, I expect to be called back. I don't expect to never hear from them again. Very, very annoying. Lacks class and corporate integrity.

I'm also unhappy with the screen. Although it has excellent resolution, it is very difficult to see unless the ambient light is bright, if not you have to tilt it at just the right angle to see anything. I don't know if it's technologically possible, but backlighting might help significantly. Also, they might want to work on providing 3D graphics.

There are also some operating system tweaks they need to make. For example, in the calculator mode Tab key will move you to the next part of the expression, but in graphing mode it appears to function the same as the Enter key and prematurely enters the expression.

There is also an operating system bug. It appears that if you "grab" something and you allow the calculator to auto power down it locks up. Doing a "soft reset" by pressing the button on the back will not unlock the system. You have to do a "hard reset" by removing a battery.

So what do I like? Almost everything else.

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.
