I've had a chance to review a couple of "modern" scientific calculators and... UX is as bad as it was 30 years ago 🤨
Hundreds of small and not so small things like:
- depending on what menu or mode you are in a simple "select/enter" moves from a button to another, or often to a combination of multiple buttons (and even that combination is not the only combination, depending on the sub-menu)
- press the "on" button to switch it on and then... "Shift+AC" to switch it off 🤔
- press "menu" to see available modes and change the current one: all nice with graphical icons you can move through using the left-up-right-down keys but then... you cannot actually select the mode you moved to with those arrows keys, you need to press a number on the keypad reading the corresponding number on the various icons 🤦♂️
