CASIO CLASSWIZ fx-991EX
Just got the CLASSWIZ. Happy to say that solve application allows integrals and d/dx to be used, allowing easy calculations of extremums.

Nice little calculator, display scree, nice shirt pocket size.

All clears, turning calculator off clears history as will a battery change. Has solar panel to compliment an LR44 button battery.

Haven't checked much more out.

Does cross and dot products of 3D vectors, does 4 by 4 matrix calculations.

As proficient as CASIO 9860gii in returning answers in fractions, pi, square roots.
