A simple leather slip case would be nice.

If you like RPN it is the calculator, or are willing to learn RPN.

The HP12c Platinum 25th Anniversary Edition (HP12cPAE) is the 2006 special commemorative limited edition model and the second official upgrade of the original HP12C. The HP12c Platinum (HP12cP version 1.0) has been improved since its released in 2003. Although the HP12cPAE is based on the HP12cP version 2.0,it would has its historical place as the 4th model in the HP12C lineage since 1981 and may be unofficially designated as HP12c Platinum version 3.0.

FIRST LOOK AND FEEL. HP has showcased this upgrade with an overall quality in both the looks and feel department. The "new" retro-styling and colours of the HP12cPAE closely resembles the exterior of the silver plated HP11C, a made in the 1980s HP scientific calculator cousin of the gold HP12C. As a bonus, HP had made this a special purchase for the fans and new owners by including a nice black 25th anniversary "PDA" style leather pouch with the HP12cPAE. The overall construction is firm and solid and the improved keypad buttons has a very nice tactile feel indeed.For better viewing, users can now adjust the contrast of the clear LCD display screen.

WHAT'S NEW? Since the HP12cPAE is faithfully and conservatively built on the time-proven functionality of the HP12C, existing users should not expect to see any major hardware and software improvements. However,it is evident that HP had listened to its customers negative feedback on its first half hearted attempt to upgrade the HP12C with the slow HP12cP version 1.0 released in 2004. HP had dutifully responded to its customers negative feedback on the HP12cP v1.0 and and demostrated their wholehearted effort with the HP12cPAE by incorporating all necessary enhancements which could be possibly squeezed into the package to expand the capabilities of the classic HP12C.

There's been many a good review on this calculator previously on Amazon so I won't delve too deeply into what has already been said. I will, however, off a few opinions that are gleaned fromm over two decades worth of using financial calculators, so I hope someone finds this interesting.

First, there are only three 'true' manufacturers of financial calculators: HP, Texas Instruments and Calculated Industries. Well, four if you count everyone else. But, HP & TI own the student and financial market. TI's calculators use the Algebraic Operating System (AOS) and HP uses RPN (Reverse Polish Notation) and some (the HP-12c platinum reviewed here) offer both. It's a matter of personal choice; RPN is more fluid once you learn it, but AOS is easier and flows math as you were taught in school. That said, once you master RPN, you won't go back to AOS.

Secondly, and this is my big beef with ALL calculator manufacturers. Handheld calculators need TACTILE feedback; meaning, notably, that you have to both KNOW when you press a button and, also, KNOW that when you do, it registers and doesn't do something funky (i.e. NOT register or DOUBLE register). This is beyond important and frequently overlooked by engineering types designing these calculators. Face it, a financial calculator isn't mainstream and it isn't used for insignificant calculations; they're used by investment bankers, accountants, analysts, etc. and these people have to be comfortable in the fact that the buttons 'work' and work everytime.

No one, not a single manufacturer, understood this except HP. And HP understood it to the point that their products were in a class by themselves. That was until about five years ago.

I have been using the HP12C for about 20 of the 25 years it has been around. I love the calculator, and this is why I have used it for so long. I would recommend a purchase of an HP 12C to everyone. I also recommend purchasing the HP 12C instead of this anniversary edition. I only have a couple reasons for this.

1) The keys of the anniversary edition do not respond as well as on the regular HP 12C. For example, when I turn on the anniversary edition, I have to check to make sure it actually turns on.

2) The quality of the anniversary edition is just not on par with the regular HP 12C. For example, the screen on the anniversay edition is already getting scratched up. I have a twenty year old and a five year old HP 12C, and neither of them has any scratches on the screen. Also the keys are just not as solid and they don't have the nice tactile feel of the regular HP 12C. The anniversary edition just feels cheap.

So I would recommend skipping the anniversary edition for the regular HP 12C.

The HP12C is as emblematic of financial calculators as the zippo is to cigarette lighters. It is a sort of "ultimate machine" in its class. It is small, handy, robust, and it has ridiculously long battery life. Quite simply, you cannot buy a better calculator for finance than the HP12C. If you can't find an unused older "made in USA" HP12C, this is the best one you can own. In some ways, it is arguably the best one to own, as it has some improved features over the original HP12C (a version of which is also still made, believe it or not: that's how good these things are -though the modern Chinese version is inferior in construction to the old American and Brazilian versions). I'm docking it a star (it should be more like a half star) as the old versions were somewhat better made, and because the new version could have far more features without detracting from utility or functionality. For example: I'd rather have a numeric integrator and matrix math like in the old HP15C, than algebraic notation. Algebraic notation is only useful for loaning the thing to your friends, which is not something you will want to do. Also included in my one star off is the case, which is almost completely useless. It is giant! And it has a magnet in it, which could destroy your credit cards if they are rattling around in the same bag as your calculator. I do use the case, but only to let it rattle around in my briefcase with other junk; otherwise, if it had the old leather glove style case, it would go in a shirt pocket (though it also could be used to rattle around anywhere, without taking up so much space or having a magnet in it).

It is important that anyone looking to buy a 12C establish its provenance; the platinums came in three versions. The first version was garbage. The second was acceptable.
