Microsoft's Marketing Genius?

I'm not an advertising 'creative' myself, but I'm mired enough in the industry to pay attention to what's going on.  Plus, I'm a consumer - I pay attention to advertising messages.  The message that I'm confused about in particular comes from Microsoft.  In their advertisements for WIndows XP, we were shown the infamous Windows 2000 "blue screen of death" - Windows crashing hard - with an assurance that, by running Windows XP, you'll no longer see this happen.  In effect, "what you're running now is a deeply flawed product.  Oh yes, it's made by Microsoft, but please, buy our newer product so you won't have to see that again.  Trust us."  Who approved that?

Now, we're getting new messages from Microsoft about their upcoming operating system, "Vista": "Security is paramount!  No more spyware or viruses!"  (Look at how weak XP looks when you read about Vista) The subtext here, of course, is, "...unlike that crummy XP you're using now!"

Who gets to market like this?!?  How do you sell more product by telling people that they're fools for buying your current product, but the next version will fix all of that?  According to Microsoft, we've now been burned twice.  Shame on all of us.
