Smartphone killed the calculator star. Some thoughts... and data too

[Sadsilence]

I feel smartphones are not the death for sophisticated calculators outside school life. It came with PCs/laptops and matching software (Mathlab/Mathematica etc.) Theoratically sitting in an development department with around 30 scientists, engineers and technicians we should be best target for scientific/graphics/CAS calulators. But nobody in engineers' job lifes comes even close to the idea programming a calculator for difficult solutions when sitting in front of PC with multiple 20''+ displays.

Indeed on nearly all desks there is a calculator, normally back from school days. What they are used for is number crunching for +/-/squareroot/conversion tasks. No 1000+ functions but a reliable keyboard is most wanted. Just for fun I often use an HP-41 or even an HP-45 for a week. Regarding tactile feedback they are lightyears in front compared to an HP-35S or a Prime. For this reason simulations on PC/Tablet are no solution, too.
