Longorn build 4051 on MSDN in November

From Bink:

The 7000 PDC attendees will receive Longhorn build 4051 on Monday, so I'll be providing screenshot galleries and a full review as soon as possible. But don't worry about pirating the build: Microsoft will make it available online to one and all in November and ship it to MSDN Universal customers in December. All together, that represents hundreds of thousands of copies of this important pre-Beta 1 release, floating around, and Microsoft wants your feedback. This feedback will dictate the timeline for Beta 1, due vaguely in the first half of 2004, which features change by the final release and, ultimately, when that final release occurs. According to my sources, the oft-delayed PDC build--it was originally due in early October, but held up because of a weird CD drive incompatibility issue--is rock-solid and quite usable, unlike the other alpha builds we've seen. And, as first reported here in WinInfo, no, it doesn't include the Aero user interface that the final Longhorn version will utilize.
