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.

I've had my HP-50G since 2/24/2007 after purchasing it from Amazon. I also own a TI-89 Titanium. The TI-89 Titanium is in my humble opinion an easier machine to use, but less powerful than the HP-50G. More functionality and power tends to mean a steeper learning curve, so if you want the most powerful, choose the HP-50G, if you want one that is initially easier to use, choose the TI-89 Titanium. Either way, you can't go wrong as they are both fine machines.

Having said that, here is why I prefer the HP-50G:

1. First off, it offers both Algebraic and RPN modes natively.

2. The CAS is powerful and can be set up for step-by-step simplification (collection or expansion of terms).

3. RPL is a *LOT* more powerful and (again, in my humble opinion) simpler -- you can do a lot more with far fewer keystrokes than with TI's BASIC.

4. The SD Card slot is perfect for transferring programs and HP Objects between the calculator and the PC.

5. It has a built-in Equation Library, SysRPL, as well as an ARM Assembler/Disassembler and Saturn processor emulator. (Translation: it is a Geek's "Dream Machine". :)

There are many other reasons that I prefer the HP over the TI, but those are the highlights.

There are some neat "Easter Eggs" hidden in the HP as well, including a great Tetris game. (Run the Equation Writer application, click ALPHA-ALPHA to lock it, enter MINEISBETTER, click ALPHA to turn off the alpha lock, then click the up arrow and press SIMP (F6). All of the flags must be in their factory-release setting too.) Viola - Tetris!
