Summary: I find that the Casio CFX 9850GB actually is much easier to use than the TI-83. It shows more detail not only because of the color, but I find it doing stuff that the TI does not(like showing a "hole" in the graph).
Summary: I own this calculator and I LOVE IT. It is particularly useful for performing statistical calculations, of which I do many. The only thing I would change is the color scheme of the calculator itself (and perhaps add just a few more advanced statistical functions).
Summary: this is a great calculator for pretty much anyone. It is easy to use, but can do highly advanced caculations, including calculus, stats, and finance operations. I have used it for my physics, calculus, finance and econometrics classes.
Summary: I found that this item was not the one I needed, but I had to use it cause its for my brother, hes at school. They sent a GC items its price is less than the GB calculator, at the end I was shock, cause the price i Paid for the GB is the same price the GC costs...
