It might be worth mentioning that things deteriorated swiftly when IBM
insisted that Microsoft, who was writing OS/2 for IBM, write the code
specifically for the 286 processor. Bill Gates personally invaded the
Armonk IBM headquarters and basically told the IBM execs that they were
making a colossal mistake. When IBM refused to back down, Gates gave
them what they wanted. The rest is history. IBM signed their own 'death
warrant'. Remember, Gates once offered to sell DOS to IBM for $10,000
dollars, and IBM turned him down.

First of all , I would be careful who I called an idiot. Secondly, you
obviously have no business knowledge. Products, whether they are cars,
drugs, etc. are improved and reissued to the general public. That is
just the name of the game.
