Today's the big day, and as part of their $500M ad campaign, Microsoft enlisted Yahoo CEO Terry Semel to tell analysts that:

We've very proud of the tremendously heroic team of developers and executives that have been dedicated to building Longhorn for the past 8 years. I'm also happy to announce, that due to their incredible efforts, Microsoft is shipping Windows Vista TODAY - a full month early, ahead of schedule!

In after-market trading, MSFT stock appreciated by 7% on this surprising upside in the schedule.

Um... not.
