Maybe. But in my experience very few people ever use a calculator - and the fewest in engineering. Be it real hardware or some app or emulator. So giving those people a snap on keypad will not change much. And those who use the calculator for household calculations (like "the recipe says three eggs per pound of flour and I want to make a cake with two pounds of flour - so how many eggs do I need?") do not care about tactile feedback. They don't get that whilst texting their friends either.
