HP Prime - video review and initial impressions

Regarding the bug fixing on the Prime -- the developers are actually very active in many user forums and have been very receptive to users' requests, comments, criticisms, etc. I am confident that they are continuing to provide new features, bug fixes, and maintain their new calculator.

Hey - I just wanted to say thanks for the videos. I just got my HP Prime today. I love your videos and I hope you do a LOT more - because I can learn a lot more from watching your videos than from reading a 549 page .pdf of a User's Guide. Keep up the good work!

I have had an HP 20 S scientific calculator for many years and just love it. I just bought an HP Prime recently and it is great too. One of the features about HP that sold me completely is the firmness and precision of the keys. There is no slop. Some calculators have their keys wiggle around in the slots. They just feel so crudely made. But the HPs are brilliant. It is a little different to my HP 20s but I will get used to that. The only thing I don't like about it is the slide on cover. I prefer the vinyl cover of the HP 20s. Only a minor issue though.

Thanks a lot! Great review! Helps a lot to make up my mind.

Very cool. And it looks like it'll be very easy to upgrade the Prime. I watched the Q&A video from the 2013 HHC meeting. Fascinating!

Great review, thank you very much sir!

Thanks very much for you reply, I appreciate it as well as the great videos.

In CAS mode, the introduction of any decimal value is considered as an explicit switch into approximation mode. If you type 5pi/2 instead of 2.5pi, then you will get the exact value. Another option is to use the [a b/c] key (switches between approx. and exact). In the home view, the result is not exactly 0 due to roundoff in the value of pi.

Thanks for posting.

Great graphic calculator

This calculator looks so better than my TI-Nspire CX II CAS. It looks much more high quality, and provides some really useful built-in programs. Of course the TI can do the same with the help of third-party apps, but I'd rather press a button than to spend an hour in some obscure forum looking for an app with the function I want. And the built-in trackpad on my calculator is kinda wonky.

And thank you for the comment!

How do you have it calculate a min or max in graph mode? The nspires can do it, the classpads can do it and I cant figure out how to do it on this.

hey how do change the screen color because mine came with the the screen back

i have the same calculator but i have seen that for the differential equation you cannot insert the initial condition, and many time the solution is not comprensible, i mean that the solution is not compact... i have also choose the option "maximum semplification" but doesnt change anything. same problem with the differential equation (derivate) you know something about that? thx

I was looking at these earlier today and pondering the thought of getting one; unfortunately, it appears that NONE of my legacy HP48SX/GX/50G RPL programs will run on it. That stinks something fierce as I've written a ton of programs for them in the 24-plus years since I got my first RPN calculator, the 48SX...

Not that I am aware of -- there is still a lot about this calculator that I am not familiar with and am still learning, though.

RSN... I'm wanting to buy an HP prime but was told to get the most recent build firmware wise and hardware wise...Where can I get the most recent version of both? Thank you, Stefos

I have started to use HP calculators since 17 year before and I think that the Prime is a toy. But when you show the program editor I feel I must to grab one of this. Is it not so plastic-feel? In the beginning of your video when you put it on the desk the sound too "plastic-like". The key clicks are the physical sound or beeper? The keyboard colouring not so sharp like on earlier calcs - it is not so confusing?!

How do you convert feet to metic etc?
