Summary: Better than the TI
Comment: 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.

Comment: Works like a charm. Much easier to use than Texas. Comes with good manual.

Summary: Great sometimes, others...
Comment: 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.

Summary: Black and White display, slow processing
Comment: 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.
