THE  QWERTY  BIAS ....   

                  THE  DVORAK  KEYBOARD  IS  OBVIOUSLY  MORE  ERGONOMIC
                  BUT  TYPISTS  STUBBORNLY  REFUSE  TO  TAKE  ADVANTAGE
                   OF  IT'S  INHERENT  EFFICIENCY .... MANY  TYPING  TEACHERS
                  DIDN'T  WANT  TO  LEARN  A  NEW  SYSTEM .... THE  QWERTY

                  KEY  LAYOUT  INTENTIONALLY  SPREAD  THE  COMMONLY  USED
                  LETTERS  ALL  OVER  THE  KEYBOARD  TO  REDUCE  KEY
                  JAMMING  ON  EARLY  MECHANISMS .... THE  DVORAK  CONCENTRATES
                  FREQUENTLY  USED  LETTERS  ON  THE  HOME  ROW ....
                  LESS  ''SEARCH''  AND ''SELECT''  THERBLIGS .....
                 
                  MANY  TIMES  INFERIOR  OR  OBSOLETE  TECHNOLOGY  IS
                  RETAINED  BECAUSE  OF LAZINESS,  FINANCIAL  INVESTMENT  OR
                  N.I.H. (NOT  INVENTED  HERE)  BIAS ....
