I've said some stupid things and some wrong things, but not that. No one
involved in computers would ever say that a certain amount of memory is enough
for all time ... I keep bumping into that silly quotation attributed to me that
says 640 K of memory is enough. There's never a citation; the quotation just
floats like a rumor, repeated again and again.

Do you realize the pain the industry went through while the IBM PC was limited
to 640 K? The machine was going to be 512 K at one point, and we kept pushing
it up. I never said that statement - I said the opposite of that.

I have to say that in 1981, making those decisions, I felt like I was providing
enough freedom for 10 years. That is, a move from 64k to 640k felt like
something that would last a great deal of time. Well, it didn´t - it took about
only 6 years before people started to see that as a real problem.
