I am a math teacher at a new private Bronx high school, and compared the TI-83 with the Casio in numerous regards before deciding which one our school would use. Hands down, the Casio wins, and it is cheaper as well. Note - I do not work for Casio or TI.
A) The calculator is more user friendly. The options are menu driven in a more intuitive way. What took me a minute or two to locate and figure out out the TI, took less than half the time on the Casio. Don't trust me- see for yourself.
B) The Casio is slightly faster than the TI
C)Features: The casio adds a dynamic graphing system (lets you change a coefficient and watch the graph change), which is very useful when teaching. I also like the EQUA feature, which lets my students calculate 2/3 equations, 2/3 unknowns, and solve quadratic or polynomial equations. Maybe the TI does this too, but I couln't figure it out.
D) The color thing I suppose is nice, but I use the CFX-9750, which is black and white and cheaper.

The only downside is that most colleges use the TI's, unfortunately. I liken it to most places using Microsoft when there are better alternatives out there (monopoly power). Anyway, a student who uses the Casio can do anything the TI-83 can do.
I'm a big fan, and my students seem to like it.

This calculator is as good or better than my TI 83 plus for much less money. Full price this calculator is only 49.99. I found for even less elsewhere. The graphical icon menu makes it very user friendly without having to study the thick manual.

The Casio fx-9750G PLUS is a great calculator for some things, terrible for others. Doing polynomial equations is simple, expecially when compared to a Texas Instruments' version. On the other hand, I have yet to figure out how to do a standard deviation. Keep in mind that if you're in high school, your course is almost definitely using a Texas - I can't tell you how many nights I've spent poring over the manual figuring out how to do the simplest of operations, while those with Texas Instruments know how to do it in a matter of minutes. If you're using it outside a formal math course in a situation that doesn't require too many complicated operations, it's a great calculator - I highly recommend. But if you're Pre-Calc or up, do yourself a favor and go grab a Texas.

This calculator does everything the TI-83+ does and more. (I was very hesitant about purchasing this calculator, because there were some features I had to have for class, but so far so good.) Unlike the TI-83+, the menu is very easy to use and understand.

I bought this version because it was cheap. It is very strong calculating machine compared to older generation but its lack of color and slow processing are great disadvantages. When you plot multiple graphs, the black and white display is a troubling. It is more so when you labor to spot the black tiny cursor on a black line. The slow processing is problematic during exam taking.

The other drawbacks are:
1- The manual is written backwards. You read instructions on how to enter data to find out that the notation would need more search to understand their meaning. The simplest thing such as turning on and off is cumbersome. The power key is colored like the rest of the keys, while the alpha key is colored in red. Turning the device off requires two keys, Shift + AC/on.

2- The F1-6 keys need longer time to relate what they do to the mode menu. I discovered their function by mere coincidence.

3- If you are looking for fast solution by using the index, you would not find terms such as exponent or factorials. It might take a whole day to learn how to get around these simple calculations.

4- Syntax errors appear on the display without any hint on the kind of error or on how to go back to previous step. You might have to experiment with the AC/on key or Exit key to get out of that.

I was recently in the market for a graphing calculator. I did quite a bit of research and was not at all pleased with the cost of most models. Then I found Casio FX-9750, and I did not hesitate one bit with the purchase. I like that this model does just about everything the TI-80x family does. It did not come with the computer interface cable, but that was not an option I was considering anyway. I wanted something portable that could do the typical math functions one would find in high level math courses, and more advanced features not common in a scientific calculator. For example, matrix calculations are handy for 2 and 3 variable equations, which are common in most math problems. Anything higher should be done on a computer anyway. The seller was prompt in fulfilling the order, and I will look them up again if I need to purchase a similar calculator.

Given the price I paid for it, I found this calculator very easy to use. It is a pleasure to work with. I'd recommend this calculator to anyone. The TI series seems to have much more appeal and I can't understand why. Casio calcs are excellent.

I have used this calculator for 3 years, and it been of great service to me. The icon-based UI makes things much easier to find and use (there are also hotkeys you could push for faster access, they're on the lower right corner of the icons). I like the screen, it has blue on green text, and it's a higher resolution than the TI-83 (I haven't seen the screens on the newer TI models). Overall it is more user friendly, with some exceptions: instructions in math class, and programs and games. Most if not all math textbooks have instructions for TI calculators, which dominate the education market. There aren't games that are graphically based like the TI calcs (Then again, you shouldn't be playing games during class), also programming is somewhat annoying to do, because all the options are handled by the Function keys. I prefer the Casio over TI (based on the TI-83, I haven't tried any other models), because of its user friendliness, and its price.

Very specific instrument. If you need a graphing Calc, in my opinion this is the best "cost efficient"

I have used this calculator for years since I started high school now in my third year at the jc and in precac with trig and i can still use it for this class. only thing is I am the only one who has this in my class. battery lasts for awhile. Great for people who want a cheap graphing calculator that works well is easy to use and has many things it can do
