If the portable math-machine really were something that people felt they needed, you'd see iPhone apps that were actually useful: the hardware is far more capable than the piddling processors they're putting in the math-class toys, or you'd see the prices of dedicated hardware drop into the $10-$20 range that scientific calculators have been in for decades.
I can't comment about the availability of iPhone apps, but on both my old Palm Treo and my current Droid, I have a fully functional emulator of the legendary HP 48G/GX running a free ROM dump from the original calculator (with HP's permission, no less).
Apart from tests (where cell phone use is rightfully banned), I can't see much use for dedicated calculator hardware, but there's still a considerable need for portable math-machines.
