I wonder if: 0) any businesses are successfully using calculator numbers in their marketing? Like a clown service that hands out business cards with their phone number 5376616? 1) there are any non-English languages with a substantial amount of calculator words? It's not like there's some inherent bias the Hindu-Arabic numberals themselves should be expected to have in favor of upside-down English, although the seven segment display was developed in the US, so perhaps there's some argument to be made from that angle.
