Strongly agree. There's a surprising cultural difference between the two. As a software engineer in a different hardware company, I can see where the fault lines are, and it takes continual management effort to make it work properly.

(I note that if we had an "open" GPU architecture in the same way that we have CPU architectures, things might be a lot better, but the openness of the IBM PC seems to be a historical accident that no company will allow again)
