RE: Beware not to buy HP Prime, if you are engineer!
I enjoy the spirited discussion on the pros and cons of the HP Prime and it's suitability to various markets and uses. Each person has their own preferences. What's great about an open and free dialogue is pressure testing a hypothesis and defending your position. Much of it is situational. Some is historical. A successful product's longevity is in the end, how well it is accepted and how long will it endure in the market (i.e. HP-12c). The Prime does have the ability to change as it matures. Perhaps there will be a next version (Optimus Prime?) that addresses some of the issues and concerns raised here.

I am also an RPN user, it is much simpler for me. My first HP calculator was a 34C. I wonder just how popular RPN is or isn't with younger generations. The Prime, of course, offers both RPN and algebraic systems. It really depends upon the person. And yes, the generation someone is from has a big influence. Personally, I am still surprised that the majority of calculator users don't prefer RPN. But, that is just me... |

Is RPN/RPL really for for retired users/engineers? Btw, RPN/RPL is possible with the prime, settings, like the HP50G. Optimus Prime will be with voice control, and hologram, very probably. |

It has an 'unlimited' stack, so a bit like RPL, but doesn't support lists and other non-numeric values, so more like RPN. So, while a bit like this and a bit like that, it's not really much like either at all. Oh, and no programming.... except in HPPL, which is however actually quite nice, once you master the foibles (this last little bit is only theory only for me; I have mastered nothing on the Prime). --Bob Prosperi |

Not being able to program in RPN/RPL is a deal breaker for me. As all us old RPN people retire, there is less and less demand for RPN programmability, and the Prime becomes more viable in the engineering market. It not the age, I'm 40 years less experienced, but for my brains and how my head works the Obviously I wouldn't want to program a monolithic windowing OS with the RPL, but for (interactive) mathematical environment it is a god like. |

RE: Beware not to buy HP Prime, if you are engineer!
Any Purist RPNer who has ONCE type anything with ' ', EQW, MTRW has contributed and justified why Prime must exist and continue to do well as Hp retired your beloved 50g.
If Prime is sub par try take out O key from 50g. |

When the RPN stack is full and something new is pushed onto the stack, the top level is lost, just like traditional RPN. But like RPL, when anything is dropped, the size of the stack shrinks instead of replicating the top level.

Similar to RPL, Prime's RPN does support lists and other non-numeric values: { 1 2 3 } Enter 2 * --> { 2 4 6 } "ha" Enter Enter + --> "haha" (Like RPL, the first Enter terminates the command line, and the second Enter performs a DUP) <0|ɸ|0> -Joe- |

RE: Beware not to buy HP Prime, if you are engineer!
[/quote]There is no [1/X] on Primes keyboard it should be enough for a proof.
What I have been wondering is that why it was not made in the way that it would have been delivered with two "memory boards" one for the educational phase with "lights for the exam mode and burned in ROM environment" and another board with more of the 48 mentality of do it all. Still it doesn't have inverse key... no use. I like it though, it is better in mechanical sense (from pictures) than what the 50g is and also the size of the unit is one step to the right direction .... smaller. [/quote] What about blue-shift and the divide key? It shows x^-1, no? Cheers, John |

RE: Beware not to buy HP Prime, if you are engineer!
There is no doubt that the HP Prime is the most powerful handheld ever released.HP Prime can support apps which can be customised to large extent with its large color touchscreen.Unlike the HP 50g with poor graphing,there is no scope for such apps.Apps developed for the prime can be beneficial in all disciplines-but they are still under development like the prestigious AutoCAD for the HP Prime which is currently under development.With assistance from Moravia Consulting and HP ,this app is being developed by a special team who have expertise in this profession.
It will include all aspects of Engineering,Sciences. Permanently banned |
