RE: CASIO 90+E vs HP Prime
Looks like the FX CG 50, but that can plot all sorts of 3 d plots, you select "TYPE" and the enter equation starting "Z=" , i thought this was absent at the start myself.
one of the other features i like is that in the 2 d plots you can plot in polar and rectangular at the same time helps me sometimes. speed wise it is no where near the Prime but is a good calc. it made me buy fx CG 500 to try, which seams limited to one graph in 3D but stumbled upon almost 80 digit precission.
