A main aim for this was to have a calculator/device with a reasonable screen display. There are already commercial calculators of course, the expensive ones have good displays and often programmable (Python, Basic), but the cheap ones are tiny and crap to use !! The 3.5 inch is still not that big, but long equations will probably be used in programs instead I guess. Wondering if spaces should be enforced. Who uses calculators these days anyway !!??
