That 30X Pro and its manual sure look tempting. Even with its $40 sticker price, I'm tempted.

I'm even tempted because of its looks alone. I'll admit. At times, I'm tempered to, on an impulse, just hitting the Buy Now button. Before I do that, between the 36X Pro, Sharp EL-W516T, Casio fx-991ES Plus, fx-991EX Classwiz, fx-115ES Plus, which are comparable or superior to the 30X Pro MathPrint?

Thanks.

I have TI30XPro MathPrint and CASIO fx-991CEX/EX. My opinion:
- TI has no MODEs, means you can use any data in any calculation, on CASIO you can't.
- TI keeps memory and history if turned OFF, CASIO can't.
- TI has real user defined functions f and g and you can use it without limits, CASIO hasn't, you can use it only in TABLE mode on CASIO
- TI can calculate with f and g in any calculation and you can construct structures like g(f(x)), CASIO do not access to f and g, it is just a label in the top of your TABLE, nothing else
- TI can calculate SUM(), d/dx(), integrate() with f and g, CASIO do not
- TI can solve more complex equations, like f(x)=your function, g(x)=d/dx(f(x),x), then you can construct second derivative and you can solve it numerically for finding inflections, eg.: (g(x+d)-g(x-d))/(2d)=0 and SOLVE
- You can do it with all complex number functions also
- I guess with all other functions, eg. base calculations, on CASIO you can't
- List based data editor on TI with user definable functions (L1, L2, L3) including any math function of the calculator (eg. L1 is frequency, L2 is magnitude, L3 is phase of your f(x), where f(x) is a complex argument frequency response function) which kept in memory until delete instead of spreadsheet of CASIO with limited capability of access to calculator functions which delete if you press ON or calculator turned OFF


If you USE your calculator, I'm sure you can make your decision. If you a collector, buy which you want.

If you want a short answer: TI-30XPro MathPrint is a TI-83 with no graphics. And powerful as hell. Sadly, CASIO make toys, I can't understand this.
