"ecks" or ten?
Apple might want us to think that iPhone X is pronounced iPhone 10, but I wonder how many people will follow that instruction? There's no context to indicate that X is a roman 10 and no "tradition" of the use of roman numerals other than OSX (which I invariably hear pronounced by most people as "Oh Es Ecks" anyway)
Was OS 9 ever called OS "icks" (South Africans talking about OSX aside :-)) Will the next OS or iPhone be XI, pronounced chi or eleven? Greek or Chinese pronunciation of Xi?
