 From Watson’s memo:
 
     Last week Control Data had a press conference during which
they officially announced their 6600 system. I understand that in
the laboratory developing this system there are only 34 people,
     including the janitor. Of these, 14 are engineers and 4 are
     programmers, and only one person has a Ph.D., a relatively
junior programmer. Contrasting this modest effort with our own vast
     development activities, I fail to understand why we have lost
our industry leadership position by letting someone else offer the
     world’s most powerful computer.

Per Wikipedia, Cray's reply was sardonic: "It seems like Mr. Watson
has answered his own question." 

 
While IBM did not appear to understand the wisdom in Cray's remark at
the time - that a large organization can have internal politics and
communications overhead and other things that hamper innovation - it
did _eventually_ learn its lesson.
 
So when it came time for IBM to make its mark in the new, emerging
field of microcomputers, it had a small team, working in isolation
from the rest of IBM, go and design the IBM Personal Computer in all
its 4.77 MHz 8088 glory.

I don't like how IBM screwed interrupts architecture of IBM PC,
completely ignoring Intel's recommendation to assign hardware
interrupts to INT #32 and higher.
The unnecessary mess they created had negative effect for a long time,
15 years at least.
Also I am not sure that at time (1981) 8250 was the optimal choice for
UART chip.
