I don't think that Jim Allchin published the PDC 2003 Video with Hillel Cooperman on the Official Windows Vista Blog in direct response to Parts One and Two of this series. However, I want to make it clear anyway though that I don't dispute the fact that MS figured out a way to deliver on most of the promise of Longhorn. The heart of my argument that, if Microsoft really considered that the Longhorn project was dead internally (which I corroborated from several different MS employees who I will not name), then they should have been more open about that publicly. And if Microsoft considered XP SP2 a full-fledged OS release, maybe that's what they should have called it.
Just so that I'm clear on the subject.
