I apologize if this has been covered before, I was unable to locate anything in the search function. Oh Ekhs Tenh or Oh Ekhs Ess & please... WHY????? I've heard serious Mac geeks correct me when I referred to it as 10 "It's an X, not a 10." I've heard Jobs refer to it as 10. Coming after OS9 that does make sense... but it IS the letter X. Thank you for your responses.
