Why I Like the 50g

* The Controversy

If you google "TI v. HP" you can find dozens of discussions by partisans of both brands of
calculators arguing for the relative merits of the their favorite model. These days, the two models
under discussion are the TI-89 from Texas Instruments and the HP-50g from Hewlett-Packard. Almost
inevitably, the discussion goes straight into whether the Algebraic or RPN entry method is better.

I can summarize the argument pretty quickly: "RPN saves one or two keystrokes." "Maybe, but
Algebraic is easier to learn---it's just like the way you would write it." From there, someone might
mention the number of built in functions for each, 850 versus 820, or the speed of solving an
integral, 1.2 versus 1.1 seconds.

I find these arguments almost completely irrelevant to the things that draw me to a calculator, and
I tire at their repetition. I will put my cards on the table right now. I far prefer the HP50g for
reasons I will discuss in a second. I own a TI-89 and the really cooler TI-92 plus with the full
alphabetic keyboard, and they are both fantastic calculators. But the HP-50g is "fun" in a way
that's hard to explain in a post. It is *not* RPN, or at least not RPN in isolation from the whole
ecosystem of the HP-50g, that makes it fun.

* The Stack

I don't know why but the HP's stack hardly ever figures into these discussions, yet to me, it is the
indispensable facility of the HP-50g that gives it its elegance. You probably have some idea of what
a stack is, but if you don't the concept is easy, but powerful.

It's 10/5/06 and I'm editing this review right up front with the first paragraph, because this little calc has a problem that I hadn't noticed initially. The new HP keys, as I describe below, are great. They have a solid click and a good rollover ability - meaning that you can push the number 1, then push the number 2 before letting go of the 1 entirely, and you'll still get "12" on the screen. That's perfect. Here's the downside: Rapidly enter the number "1100." Click-click-click-click. And yet my screen says "10." Why? Because a rapid double-click of a numeric key results in the calculator noticing only the first click. If a typewriter worked that way, I'd be attending metings every day instead of meetings.

**UPDATE - 10/14/06** One of the commands available, not documented in the 50g material, but documented for several earlier HP calculators, is a KEYTIME command. Quite simply, replacing the default keytime with "500" eliminates missed keystrokes. This corrects the problem I described above.

And now back to my original review:

First, the keypad issue has been addressed with this model, and each key has a feel that is similar to the HP41 - just about perfect for data entry without needing to look at the keypad. Now all that's necessary is for HP to return to the complex keys that allowed for print both on the top surface and the beveled edge; that would allow for some improvement in the user interface. But overall this is a major step forward from the HP49 line.

Next, the display is bright and legible with good contrast. These multiline displays still aren't quite as good as the single line displays from years past in terms of visibility at odd angles but we're coming close.

At first I was somewhat disappointed with the HP50G, since it essentially has the same form factor and functionality as the HP49G+ (which I also own). Just changing the color doesn't justify a new model designation, IMHO. Wait a tick... the keyboard seems a bit better... played with it for awhile... switched back to the HP49G+... ack! I never noticed how horrendous the keyboard was on the HP49G+. The keyboard on the HP50G is velvet in comparison. If you have been frustrated by the clunky, clicky keyboard on the HP49G+, then the HP50G is the answer. Otherwise, stick with the HP49G+, since it is essentially the same calculator.

The HP-50G is Hewlett Packard's latest offering in the line of top-end calculators stretching back through the HP-49 and HP-48, all the way to the "dawn-era" of scientific calculators in the 1970's, when the HP-65 and 67/97 defined "high-end" calculators. This device is so powerful, and has so many potential capabilities, that in many ways it is much more than a "calculator"; better to call it a handheld "computer", one dedicated to mathematics, rather than general purpose use like a PDA. The HP-50, at only $115, is a lot more affordable than most PDA's too.
In fact, the HP-50g is so powerful that most owners will never tap it's full capabilities. Programing it in SystemRPL or Assembly language opens up an instruction set of some 3000 commands! Even if you don't write software for it, the HP-50g has enormous capabilities to solve complex algebraic and calculus problems right in the built in Equation Solvers and Computer Algebra Systems (the CAS).

For users of more traditional calculators, the HP-50g may seem intimidating , if not overwhelming. One problem that I had right off the bat is that much of the keyboard is dedicated to programming and equation solving, rather than simple math functions. Unleashing the potential of this beast requires programming, whether you do it yourself or buy commercial software. The HP-50g can of course be used to do simple math, but that would be like using a 12 pound sledgehammer to set finishing nails.

Noteable features:
-Programs and user data can be stored on SD flash cards, up to 2 gigabytes.
