I'm amused by the number of commenters who are jubilously vindicated that OS X has a nasty bug, as if that somehow makes Windows better.
[Nitpicker's corner: Dispute "very."]
Saying that this news (which should be spread since it can lead to quite unpleasant problems) is being promoted by Microsoft fans doesn't take away from the severity of the bug. And the fact that this news is out certainly doesn't take away from the disaster that is the Sidekick story.
Take a step back and try to avoid looking at it from a "Microsoft is a bunch of evil jerks" perspective.
