Arguably the most capable calculator ever made
It was love at first sight, when I saw this shiny new HP 41CV in a store window back when I was 15. I had used a 32E before and I knew I had to have this 41. Thirty-four years later, my good old CV is sitting on my desk at work, with a CX (bought a month ago) next to it. The CX is basically a CV with the Extended Functions module (which I bought for my CV at the time) and the Time Module built in, and some other minor extras. So what follows goes for both. The love has grown over the years - this machine helped me through 3 years of high school and 5 years of engineering studies, and has been my companion for all the years after that. HP has made awesome calculators over the years, but I keep coming back to the 41. I have a range of others: 35, 45, 21, 25, 67, 37E, 38C, 12C, 15C, 28S, 10B, 14B, 17BII, 20S, 32SII, 42S, 50G and even a WP 34S - they are all fine machines, but my daily workhorse is the 41. Its expandability is fabulous and without comparison - wired, IL and infrared printers, IL tape drive, IL diskette drive (imagine the splash a 3 1/2" diskette drive for a calculator made back in '83!), a long list of expansion modules, a card reader, etc.. I have and use all of these regularly, which is another testament for the legendary HP quality. Back to the 41 though - it has a keyboard that's the best ever, bar none. Thousands of user-written programs are available for it, it still has active internet groups and several websites dedicated to it. It has been on several space shuttle flights. Yes, today's calculators are an order of magnitude faster. Yes, they have graphical displays and loads more memory. Yes, they're cheaper than a 30-year old 41 (!). But they're not nearly as much fun to use. Enough said.Verified purchase: Yes

Does this calculator really need a review?
If you are actually considering buying an HP-41CV, chances are you are over 50 like me, and you simply *loved* your original HP-41CV to death. I used my '41CV for 23 or 24 years on the job, i.e. every day. Failure of my earlier HP 11C calculator due to keyboard deterioration (you may substitute 12C or 15C here) after only about 5 years led me to buy a 41CV. I've written about 25 simple programs for it, actually a couple of my programs are iterative and more complex. This little soldier outlasted my 11C by almost a factor of 5 thanks to a MUCH better quality keyboard. In the end, it still was the keyboard that failed on my original 1987 41CV, but 23 or 24 years of everyday use is pretty respectable! There are assuredly newer, more whizzbang graphing calculators (etc.) available now, but at this point I bought a used HP 41CV simply because it does everything I need AND I know where every freakin' key is without hunting. The Pi key has been Shift-zero for so many years I don't need to think about it. That's one of the two top reasons for buying one of these: #2 - If you can find a "lightly used" one, that keyboard has lots of years left. #1 - You KNOW where all the keys are ('cause you've used one for 20+ years) I hope the foregoing definitively provides a NO! answer to the question of whether this "product" even needs a review.Verified purchase: YesCondition: Pre-owned

the best calculator ever?
The HP-41C (of which the CV and CX models are impoved followups) is considered by some to be the pinnacle of programmable calculators. What sets it apart is the wide variety of expansion modules-- magnetic card reader/writer, infrared bar code reader, printer interfaces, ROM modules preloaded with application-specific programs, etc. It is one of the earliest calculators with alphanumeric support. About the only thing it doesn't have is a large enough display for graphical output. Thie HP-41C/CV/CX was sold at the time when personal computers were becoming popular and affordable, which ultimately led to the de-emphasis of further development of calculators at HP and other companies.Verified purchase: Yes

HP41 Possibly the best calculator (computer) ever made
The HP41 was an innovative product of its day. For those who couldn't afford a personal computer, had a desire to program, and needed portability, the HP41 filled the need. It's more a computer than a calculator, supporting external devices, such as disk/tape drives, magnetic card reader/writers, ROM programs, and printers. It's keys are firm and responsive. Good enough for me to use by touch as a ten key for several years as I worked as a CPA. I also like the Financial Pac ROM, that I use for date math and NPV calculations. I also prefer working with RPN and its memory stack. There have been other good HP calculators made after the HP41, many faster, but all are more focused on a specific target market with far fewer features.Verified purchase: YesCondition: Pre-owned

Best programmable calculator to this day
The HP-41 with all its variants is an icon in the history of programmable handheld calculators. HP did it so well that with all its peripherals, it was designed to be a complete computing system with different I/O options. Its RPN programming is simple yet extremely powerful.Verified purchase: Yes
