RE: HP Prime or HP 50g
Hello,
"Crap" I have owned All 48 models, and made the 50g. I have also created Prime... So, here is my opinion, for what it is worth :) I have a hard time thinking about anything that the 50g could do that Prime can not (some IO maybe...) Prime is better than the 48/40 series in prety much every conceivable ways. More features, faster, larger screen... But, it does have some failings. 1) Pure command line number crunching is not as easy as with the 48, due to RPL. I, interestingly enough, find myself often doing operations step by step (using Ans) because RPN is not there. 2) Simple Unit manipulations is not as good as what you get on the 48 with the menu/shift menus shortcuts. 3) The Prime Color screen is not as visible in broad daylight as the B&W 48 one. (1) is, in lots of ways a side effect of the CAS and the fact that Prime is much more geared toward symbolic math. And symbolic math does not mesh well with RPN "older" HP calculators were number crunchers. Prime and modern math are symbolic manipulators. And this is a main reason for the shift there. (2) We know that this is an issue, but we have yet to find a good solution for it :( (3) This is a pet peeve of mine, especially with cell phones that are unuseable outside... Unfortunately, the color is there to stay at this point in time... Anyhow, this being said, Prime's prime target (yes, pun intended) is symbolic math, education and a more "modern" UI (read mobile phone like). And this, like it or not, drives a lot of the decisions... Prime is insanely powerful, and can do prety much anything. It is also way easier to "learn" than the 48/50 series ever was. Which is a must for a generation that does not know what a user manual is... Aout libraries: Yes, they are a lot of libraries for the 48 series. The 48 series is also nearly 30 year old by now. They libraries did not come imediately. They are great programs for the Prime, but noone has yes spent the time to work on EE stuff. All is needs is someone to come forward and start developing them. About NUMWORKS: NUMWORKS is a very limited calculator at this point in time. They are a couple of great UI in it, especially for the stats, but altogether, it is way behind Prime at this point in time. Cyrille Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.
