 The best HP RPN Calc in 20 years! November 14, 2008
T. Hanson (USA)
My personal opinion is the 42s was the pinnacle of pocket sized excellence. The larger models afterwards are too big physically to be handy. I use: 42s, 35s, 48sx, 33s, Ti-89 (in order of preference). Primary use is electronic design, base conversions, using many self-coded macros/functions/programs in the calculator.
The 35s offers a "HP 42s Lite" in a way. In all, I miss the label/menu interface used on the 42s. I'll buy another 35s just in case, though, since HP seems to be drifting away from making Good Calculators, and compromising to the the "= user". The 35s is the first sign I've seen in 10 years that HP realizes the market for a True Programmable RPN Calc.
Things to note about the 35s, vis a vis 42s and other "classic" HP designs:
Only Single letter/number storage/program labels. HP Had Word size labels in 1990 on the 42s, this calculator is the same physical size, with more inputs (left and right shift, the 42s only had one shift). With the advances in semiconductors, I am shocked to see this (mild) limitation. In actual use, I haven't used over 30 program names, but it is very nice to give them a meaningful 'name' instead of a letter/number label.
Others' comments detail some minor usage issues, many are due to incorrect mode chosen (RPN/ALG), some are actual annoyances (hex/binary entry).
The 35s gives me most all of the functionality of the 42s, many extra features over the 42s, and I don't need to spend $400+ to get it at an auction.
Bulletproof Construction. Calculator is solid, keys have the snappy tactile feel famous of HP. I have no doubt this too, like my 42s, will last for Decades of use.
The 35s Comes with the best hard/zippered case I've seen on "consumer calculators".
If you are a student, keep this in mind: In everyday/Real World work since college, I've used the SAME 42s in my daily environment (17 years). I haven't really touched the graphing 48sx. This is a large "feature" one needs to pay attention to, and the reason so many people "collect" HP Calculators, as well as use them. Once you are used to one calculator and functions, switching to another slows you down A LOT. I haven't run into a situation where an "Algebraic" Calculator can do something faster or simpler than an RPN calculator, both in keystrokes, and processing time.
If you are used to RPN, you will not regret this purchase! (unlike the 33s...)
If you are used to an = sign, but want to learn RPN, then this is the perfect choice for transition!
I am hoping for the release of a 42sII, but I'll happily survive with the 35s until then.
HP Power November 12, 2008
C. Gaige (Denver, CO)
I had an HP for over 20 years and loved the RPN. No problem there, but the calculator buttons began to get less dependable. Replacing it with a newer HP was the right answer. Lots more power here than I will ever use, even though I'm an engineer. The instruction manual is on a CD - finally got beyond the situation where the instruction manual was bigger than the calculator. I love it. Very easy to read, very well spaced keyboard. Clear labeling. Good Luck
Finally, something to replace the 33s trainwreck November 5, 2008
OregonBubba (Aloha, Oregon)
The buttons and display are very crisp.
The multiline display is good, but needs some improvement.
With regard to the 33s, the batteries need to be replace frequently.
The 33s is a P.O.S.
Good HP October 28, 2008
Behnam Zakeri (USA)
I got my HP35s and I like it. I own an HP41CV also. It is very easy to program it, especially they replaced the PROMPT command which you have to key in in HP41CV with INPUT key-very convenient. I am glad HP is back with its line of quality calculators. Behnam

Crockett99 (Okc, OK USA)
I purchased a HP33s to replace an 11C (mistake). The keys on the 33S just didn't feel and function right. The 35s is a perfect replacement. It has the feel of the 11C keys and has performed flawlessly so far.
