• Nothing beats RPN
  I bought the original HP-35 back in the early 1970s. I loved RPN then and I love it now. I don't understand why HP nearly gave it up after Texas Instruments moved into the market. Anyway, the HP-35S has everything I need and more. My only criticism: Why isn't there a help feature? You should be able to press and key and get instant help on it.

• Not for the feint-hearted!
  This is truly a "nerd's" calculator. It is a calculating workhorse. It was designed to separate the true math/engineering jock from the weekend dilettante and mere poseur, and the price certainly discourages amateurs--in other words, it is not for eighth graders. But, I don't know, maybe some suburban soccer-mom might buy it so little Britney can do her algebra homework.
  "Because she deserves the best"--BIG mistake lady.
  Sure you can use it to file your tax return, but make no mistake, you WILL... more info

• Kudos to HP
  There are already many good reviews here covering most of the main points, but here's my 2-cents.
  I have used HPs with RPN for many years, including 32S, 42S, 48gII, and 50g. The 35s is a mid-level model like the 32s, but with a few improvements mentioned by others. I especially like the easy entry of complex numbers using the "i" (or shift-theta) key. But the main thing that is good about this calculator is the return to good manufacturing. No more defective keys like those that plagued the 48g... more info

• And major improvement over the other recent offerings from HP
  This calculator feels more like the older high quality HP Calcs. HP has all but forgotten this market. The calculator is easy to use and has good power but the major complaint is that there is no way to store or save programs out of the calc. If you need to remove a program it is lost. a card slot or usb port would be a major improvement.
