New Microsoft Vista Ad

On which planet does this advert make any sense? (Answer that and you could be in line for a $300 million contract....)

Maybe it's the first part of a series that culminates in a knockout advert for Windows 7 in 2010 -- possible, given its very leisurely pace. (At 90 seconds, it's clearly a net ad, not a TV ad.) But it obviously is part of a series, so I assume you're supposed to figure out what it means (if anything) and guess what's in the next one.

As a one-off, it will probably go viral*, so millions of people will see it at no cost to Microsoft. But that's only half the job, unless there's a decent "payload" in the end. And so far, that's nowhere in sight....
