Customer ratings and reviews for HP 50g Graphing Calculator

Rated 5 out of 5 by Greatest Calculator of all time The HP-50G has no limits of capabilities. May 30, 2012
Rated 5 out of 5 by Great calculator I have owned and used H-P calculators from 1987 starting with the H-P 28s. I also have a 48gx and now the 50g. I also have and use PC emulators for these and a couple of other models. My main attraction to H-P calculators is the RPN entry system. I have always found this more efficient, in fact when I have to use another non-RPN calculator on occasion I find it rather cumbersome. I've tried the Algebraic entry system on the 50g and like it but still prefer RPN. At least I have the option to use either. Since I have the 48gx there was not a big learning curve in going up to the 50g, although the 50g does have many more features I am still learning about. The fact that the 50g can use an SD card is a very big plus and makes transferring files from my PC a breeze. I often write code on the emulator and transfer to the 50g or vice-versa and while the USB port also works fine for this, the SD card is a bit easier. My only complaint is that the 50g seems to be of cheaper construction than the 48gx, but that seems to be a trend nowadays. Functionally, it works very well and I am happy with it. April 23, 2012
Rated 5 out of 5 by Math just got easier I bought a calculator that I did not know how to use, but after a week with the instuction disk, I was making the grade HP made calculations much easier. March 3, 2012
Rated 5 out of 5 by big fan The 50g expands on the wide functionality of the 48g. Nothing was lost in the way of available mathematical operations and programmability. However, I do miss having the accessories like the printer and the back stand. But overall, the 50g is even better than the 48g due to the durable glass screen, the increased menu options, and improved user-friendly environment. February 6, 2012
Rated 5 out of 5 by HP50g - Missing built-in help Hello, this is most likely the most powerful calculator available on the market. Unfortunately for many users this power can not be unleashed due to the poor manuals and the poor support given to this machine by HP. Thus, that are struggling in using this calculator due to the poor documentation and poor support provided by HP might consider using the 'HELP for *all* commands integrated into the O.S.' which overcomes this weakness. It establishes a complete context sensitive help system containing detailed help entries for 764 user commands including stack diagrams, access to the command and "hyperlinked" navigation to related commands. The help can be called from anywhere inside the system. Regards, Andreas January 14, 2012
Rated 5 out of 5 by keystroke speed issue Overall, it has been a great calculator. My only complaint (which was originally a big one) is that if you pushed the same number twice too quickly it would only accept one of the entries. I searched Google and found that you can change the keystroke speed in the calculator's program. It was an easy fix. BUT, apparently, I will have to do this whenever I change batteries. It doesn't make sense to me that this isn't already done from the factory; I did not see where it could cause any harm either. HP: this is a serious matter. I can't have the calculator accepting a "10" instead of "100" just because I forget and push double zero too fast. I was just about to return the calculator when I stumbled upon the "keystroke" fix. You should fix this! September 19, 2011
