Along with the standard computer warranty agreement which said that if the
machine 1) didn't work, 2) didn't do what the expensive advertisement said,
3) electrocuted the immediate neighbourhood, 4) and in fact failed entirely
to be inside the expensive box when you opened it, this was expressly,
absolutely, implicitly and in no event the fault or responsibility of the
manufacturer, that the purchaser should consider himself lucky to be
allowed to give his money to the manufacturer, and that any attempt to
treat what had just been paid for as the purchaser's own property would
result in the attentions of serious men with menacing briefcases and very
thin watches.
