Numeric keypads on keyboards and ATM machines have "7 8 9" as the top row, whereas keypads on telephones have "1 2 3" on the top row. Both seem to have 0 on the bottom. I know the arrangement of keys on a phone comes from the two tones that combine to make it a "touch-tone phone", but this still doesn't answer my question as to *why* they are not the same. Has anyone else noticed this and/or been annoyed by it? Am I alone?
