When people
decided Steve Jobs had become a god?
Right about the time that whole "computer
for the rest of us" started...
an unreliable source, who was working in Apple at the time, said that it
was being touted "for the unwashed masses, or at least ignorant rich
folk".
Somebody was smart enough to latch onto that and change it from third
person to first person plural.
Using computer phobia to market computers was a smart move.
