I never thought anything could top my old 11c but this sure comes close. Many things are actually simpler and easier! What?My favorite improvement is that you can use the calculator while it is still in the case. This may not sound like much but I really like it.

My history with HP calculators goes back to the HP65, back in the 1970s. As the product line changed over the years -- the small 41C, the "landscape" 11c and 15c, the alpha display 32SII -- HP managed to maintain a reasonably consistent and utilitarian style.

More traditional HP keyboard style; very legible keys, nice feel

Display is shiny, less resistant to glare than other models; Minor bugs with trig functions

The HP 35s Scientific Calculator arrived on time and undamaged. The Quick Start Guide was very useful since this was my first HP calculator so I had no idea how to operate it. Within a day I was calculating my Electrical Engineering problems with ease.

+ Easy to operate right out of the box + protective carrying case + FE approved calculator

It would be even better with a bigger screen

The calculatior is superior, previous case design was of much greater value / functionality.

Engineering friendly; Excellet calculator; RPN

Case unsatisfactory

Yes, I would recommend this to a friend

2 line display; Attractive Design; Clear Display; Easy To Use; Good key layout; RPN

Can confuse theta with 0; No Matrix functions

The HP 35s Scientific Software Calculator offers flexibility and control that no other digital calculator can provide. The HP 35s Scientific Calculator has been used for years by mathematicians, engineers, and students to calculate the most challenging equations.

The software includes comprehensive help documentation that teaches the user how to use every function of the calculator; The layout of the software is identical to that of the real-life HP 35s calculator; which makes it an easy transition for professionals and students alike; The software can be...

This calculator should not be used for simple calculations; as it may appear cluttered to the average user

More expensive than others but you get what you pay for. This is for serious college students and engineers who make their living using a calculator. Browse your manual and learn a little about it and you'll learn to appreciate what it can do.

Has all the features you need for engineering work and college math; RPN is the biggest pro; If you don't know how to do RPN, learn it and you will understand why people pay more for RPN calcs; Calculations are faster and easier to understand and keep track of what you're doing

No printed manual; Manual is a pdf file on a disc; >:

I have a HP 33S and an HP 15C as well, and I bought this one as another calculator for routine calculations. I love RPN, with this calculator one can use both algebraic and RPN notation. The keys are the "classic" HP keys, easy to read and very comfortable to use.

Professionally is very practical for fast engineering calculations.

Replaced updating the HP11C
