Top three calculators ?

[lrdheat]

HP 30b RPN, great stats support (size of data base a bit limited), easy to find math operations on keys or menus (not too cluttered, not too much to remember). Programming is difficult, limited, a weak point, but looking at this question from a calculator point of view. Keyboard on my example is good.

CASIO fx-CG50 excellent math/statistics/unit conversion function set, fast (much faster than TI 84 CE, not in same ballpark as the PRIME), excellent graphing and analysis tools. Intuitive entry...rarely have syntax errors arise. Pants pocketable, but not for shirt pocket.

WP 34S amazing capabilities!...a bit to remember as result, a bit of effort required to find some operations. Unit conversions somewhat limited, matrix/vector support is limited.
