Indeed, however a non-graphing calculator and a non-graphing calculator have differences, I personally would not want to live without calculation history and enter-calculation-then-calculate system (instead of the one where every symbol you press instantly applies it to the number you have on screen, I have no clue how these two are officially called). Point being that we'd end up with a certain list of allowed calculators even if they're not graphing because they're simply not the same and some are much faster and nicer to use.
