Rated 5 out of 5 by from HP 35s scientific calculator This calculator replaced my 48s that died. I never came close to using all the features, and this has all the features I need for quick calculations at my desk. I have grown up with HP and RPN way of entering numbers.

Rated 5 out of 5 by from Great calculator and RPN is a must have. Like the two line display. I do miss the comma delimiter inserted for the thousand, million, etc upon entering a large number.

Rated 5 out of 5 by from Feels like home- almost After over 28 years with an HP32s, I finally had to replace my trusty calculator. (Which, by the way, should show the reliability and sturdiness of HP hardware.) And the 35s is just like my 32- almost. Some functions have moved on the keyboard, which is playing hob with "muscle memory" keyboard entries. (Example: I keep hitting the "5" key instead of the "8" key for "Hour-minute-second" conversion.) Irritating, but I can retrain my fingers. The keys feel firmer, with a more positive reaction. I really like this machine, and appreciate that RPN is not dead!

Rated 5 out of 5 by from Need small version I have used HP RPN calculators for 40 years and love them. I have published code for them in 170 countries for specific engineering applications. I have been waiting for 4 decades for a small version of a RPN calculator that will fit in my shirt pocket... yea, less programming function, etc... no problem... just need a smallish version to have with me all the time... never saw it... still hoping.

Rated 5 out of 5 by from Love RPN I've been using HP RPN calculators for well over 20 years. In my opinion, any serious science or engineering student will be very well served by this device. This is the machine of choice in today's market.

Rated 5 out of 5 by from Excellant The HP35s is the best scientific calculator I have ever owned. I have purchased three (3) since my first one back in 1984. The only improvement I would like to see is the function keys layout. The function keys layout is presently vertical, but was horizontal on the old models. I would like the function keys layout to go back to horizontal (like the financial calculators function keys layout is now)
