 Excellent and complex, the do-everything, top notch, HP calculator June 12, 2009

I have owned top of the line graphing and scientific calculators from TI, HP, Casio, Sharp, etc. Back when I was a student, TI's were very cheaply made and often broke quite easily and similar HP products lasted almost forever. This machine, the HP50g, continues that HP tradition and is definitely put together very well. It is also a very good improvement over its predecessor, the HP49g+ with more memory and with a much improved keyboard and improved keyboard "feel" and a much better feature set overall, including the full library of solutions from Physics and Engineering that was available from the HP48 series of machines, etc. The pros and cons as I see it are:
PROS:
1) The Hp50g has all the standard and CAS (Computer Algebra System) features that we have come to expect on such a machine, plus many nice very detailed and very mathematically advanced topic as well as course specific APPS that are already preloaded or can be added in electronically and quite simply from the HP or HPcalc or other websites. These include the ability to even perform a digital FFT (Fast Fourier Transform) as well as many many other advanced functions of a similar nature. The USB interface works with a computer and is also quite fast and easy to set up.
2) It works quite naturally with complex number solutions of equations. It can be switched in the Mode setup from a Real to a Complex number operating stance and even back again as desired or it will even prompt you to make a mode change if you are in Real mode and the answer is in fact a Complex number. If it can't perform an operation which is fairly rare it will simply repeat the proposed operation back again below the original one on the display screen as the answer. This machine is so versatile however that it will even evaluate symbolic matrices or even matrices with imaginary numbers (an Electrical engineering nightmare otherwise!).
3) This machine itself is quite fast with a nice graphical interface and resultant plotting system. The resultant plots are high quality and with the many added features available for enhancement are very intuitive for the learning process.
4) It has a nice and quite modern, curved body design that sits very nicely both on a desk or a table as well as in your hand.
5) It has a very large amount of onboard main memory, plus additional Flash memory for tackling quite memory intensive problems.
6) Although it is called a calculator, it is really a small and very fast (75 MHz) handheld computer system which can tackle problems from the most simple to almost the most complex.
7) The famous RPN (Reverse Polish Notation) and an Algebraic Operating System (AOS) as well as a so-called textbook mode are all available to be chosen depending on the wishes of the user and on the problem to be tackled.
8) The complete set of the predicted units of the solution of a complicated equation (or set of equations) can be determined independently of and simultaneously with its numerical answer(s). This is a very fine feature that I do not know of on any other calculator system.
9) As on all such HP RPN models, a very fine self-test system is available to make sure your machine is fully functional all the time and a clock (now without seconds) complete with the date, is also continuously available.
10) Finally, this machine also has a fine, onboard Help system for some, but not all of the CAS commands, if these commands are at all confusing (and there are many many commands available on this machine). It is a good HP system with multiple references (up to 3) between different , but similar commands (for example with the soft-key designations: SEE1, SEE2, SEE3, etc.), but the Help system on the newer Casio FX-9860 Slim calculator is even better in my opinion, i.e., it includes ALL the commands in the calculator (but with no CAS present on the Casio unit) with complete operational syntax details for every command. The latter Help system is even advertised as being sufficiently detailed so that the manual doesn't need to be carried around to efficiently work with this Slim Casio.
CONS:
1) Some functions that you would readily expect to be available with a single key press require instead at least two key presses, but usually with only a single shift key press first.
2) The learning curve is quite steep, although very well worth the considerable effort, but this will heavily deter some good students from learning the RPN skills that can be effectively used for your entire lifetime once they are successfully mastered.
3) The HP50g requires multiple batteries plus a backup coin cell battery in order to save everything briefly when changing the main batteries.
4) It really needs a large ENTER key (and also it should be located in the center-left location) just like on the HP machines of the distant past (and as recently included on the HP35s for example).
5) HP should also add a backlight system for viewing the screen in the dark as implemented very nicely in the new clam-shell design on the Casio FX-9860g Slim version.
 Great calculator, but not when doing things one handed May 18, 2009

I upgraded from the HP48G and while the functionality, speed and everything else has improved I feel as though the ergonomics were left out of the picture. This is going to sound strange but I typically used the 48G w/ one hand and my left thumb doing everything. In college on exams I would write with the right and calc with the left. I do the same at work. The 48G had the batteries placed in the lower portion giving a nice balance to it in one hand. The 50 has 4 batteries under the display, so it makes it very top heavy and out of balance. In addition they moved the enter key to the bottom right corner and it used to be in the middle left...there was a reason for that HP! All in all a great calculator but I wished they'd considered more carefully the reasons why the 48 series had the layout it did.

Very dandy calculator. Very quick (much faster than a 48). Keys have a very nice feel (maybe not the EXACT one that HP fanatics have in mind, but good feel none-the-less). It does everything. Integrals, etc. At the end I still preferred a ti-92 for all my math classes. But for number crunching I preferred an old&trusty HP-48 (but that's because I'm so used to the layout that when I pick up 50g I press the wrong keys). There are some things about this calculator that feel like it's a hack on top of the 48g operating system. Keys are not marked with functions. For example, hitting the right arrow, swaps the x-y registers (in RPN mode) - YET the key is not marked as such (a very important RPN function). Hitting the down-key opens a viewer to look at the element in the lowest register - again UNMARKED...
It's a good calculator, it's just very quirky; and if you truly need that complexity, you will love this calculator. Unfortunately, most people will probably be overwhelmed by it.

The HP 50G is a considerable improvement over the 49G+, mostly due to the improvements made to the keyboard. It is noticeably faster with the new ARM processor which replaced the old Saturn's. The current documentation is also quite detailed (1000+ pages). Overall, it's a perfect tool, within this price range, for all science-oriented majors. Recommended without reservation. (Reviewed by the actual user of the calculator: Duru Can Celasun).

OK, i buy this calc for a friend who is Civil Engineer, and he said me that it's the best gift he was received, and said me too that this calc is extraordinary.
