>At the time, Windows was very very primitive, they had not yet figured out how to make the windows overlap and re-paint (which we had figured out a long time before that). I actually felt sorry for them at the time because I just could not imagine how they would ever catch up with Apple, the Mac was just so much more advanced. It seemed to me like there was no doubt that they would be out of business in a few years completely replaced by Apple, it was just so obvious at the time to me.

while it feels somewhat paradoxical, reinvention of the wheel has been an extremely efficient way to move the industry forward. Probably because it is an effective way to subterfuge the incumbents, and incumbents are the most significant obstacle on the way forward.
