Digital camera Review: Excellent Calculator
Summary: 5 Stars
When I was thinking about buying this calculator I also considered the TI-89. While the 89 does have a higher resolution screen, I find the HP-50g to be superior. One thing I particularly like about it is how easy matrix manipulation is. Using the CAS to do symbolic manipulation is tough in RPN mode, but it's easy to switch back and forth so that's not too much of a problem. Programming the calculator is also fairly simple. I also find the keyboard on the 50g to be much superior to the 89.Digital camera Review: Excellent Calculator
Summary: 5 Stars
I have been using the HP50G for about a week, now. I decided to retire my HP48GX because the HP48GX is now a collector's item.
The HP50G is, overall, an excellent calculator. The keyboard has a good tactile feel with a nice subaudible click. This calculator is vastly superior to the over-rated TI-89 Titanium. The HP50G will do everything the TI-89 Ti can do and then some. The HP50G has built-in functions for vector calculus, vector manipulation (dot product and cross product) and the matrix tools are very good.
The contrast of the screen is good. You can set the calculator to put the equations in "Textbook" form (TI's "Pretty Print). But unlike the TI-89, the text is larger and easier to read.
The contrast of the keyboard is much better than the nightmare of the TI-89 TI keyboard. The secondary and tertiary functions are orange and white against a black background; very visible.
Many of the old programs needed to increase the usefulness of the HP48G/HP48GX series are now built-in. It is necessary to use the calculator in the "Reverse Polish Notation" (RPN) mode in order to get the most functionality. Intermediate results during calculations are put on the stack and you don't have to hit a stupid Answer button to manipulate intermediate results.
There are a few negative features, though.
1) Many people have already mentioned the problem of the default keytime setting being set incorrectly for fast input of duplicate digits. The fix is very simple: type 300 then press the [CAT]button, access the [--> KEYTIME] command, press [ENTER] and the problem is fixed. After several years of complaint, you would have thought HP would have changed the default setting.
2) The keyboard functions are semi-redundant. If you press the [SYMB] key you get some of the functions available from the [CALC], [ALG], [ARITH] and [TRIG] keys but not all. I get the impression that the key's were assigned to a couple committees and they didn't talk to each other. The assignment of functions to keys certainly should have been more efficient. That would have freed keys to allow for the inclusion of the double-size [ENTER] key that should be there but isn't.
I think that part of the problem is that the HP50G tries to be both an Algebraic and RPN calculator at the same time.
3) The calculator is a power-hog. After a week of hard use, my batteries are at about 56% power. There is an available program from hpcalc.org called BATSTAT that will allow you to monitor battery status. However, the HP50G will run on power from the USB cable.
4) Unlike my old HP48GX, a "warm start" is necessary to add libraries to the memory. The manual does not make that clear. Just press [ON] and [F3] at the same time and you're all set.
Despite my nitpicking, this is a great product. At the prices it is being sold for ($100) this is a steal of a deal. Do yourself a favor, buy this calculator, learn RPN (its not hard) and you'll never be sorry. This is a necessary tool if you are an engineering student. If you are using a TI, you can make like much easier for yourself. Now that Carly has been given the boot, maybe HP will get back on track with its calculators.
Digital camera Review: Excellent Graphing Calculator
Summary: 5 Stars
I had been using an HP-48G graphing calculator. After several months of use, I now greatly enjoy the HP-50G. This calculator is faster and provides several additional features not in the previous product. Information can be stored on SD Memory cards. The calculator also allows easy access to all calculator functions with the CALC button; I find this easier to use, but others may like finding functions through the associated menus accessed through other buttons.
There is a Quick Start guide that provides preliminary information about how to use the calculator and a few sample problems. A DVD provides the rest of the manual and example problem sets. I find this easy to use, however, I sometimes wish they provided all the information on an SD card that can be utilized with the calculator and some type of text reader.
