We have worked very closely with AMD, and they have broadly been very supportive of what we're doing here. As for the more general point of the peril of tightly integrating with partners (AMD is not the only one that we have gone very deep with): yes, it's a risk. But we have consciously decided that we would rather make deliberate decisions and deeply integrate than build a system composed of the lowest common denominators. Relationships are always a gamble (which is why it's important to enter them carefully!) but our belief is that the upside of a tight partnership more than compensates for the risk.
