HP50g : Symbolic solver oddities or user errors?

[Bill Platt]

Quote: seriously why there is no graphic, cas, low energy, illuminated on/off, engineering/sci/pro programmable (with something efficient like UserRPL [for quick and dirty] & SystemRPL combination) calculator with good keyboard and dimensions rougly 6½x12 centimeters (can be used with one hand and fits to pocket / slim briefcase) on the market.

Wellllll....let's just say that it is something of a miracle that there are still "6x12" centimeter machines that have any design function for this, *at all.* I think you pretty much answered the question already: Wolfram, MAPLE etc...
