XP SP3 and the SPIN!

As everyone in the world now knows Microsoft has delayed SP3 for Windows XP, until it fixes an issue with interoperability in relation to its own Dynamics Retail Management Software. I was curious as to how many companies use this software and in the last few days looked at every store I went into and to my surprise none were using it. Not even the dry cleaners...

Is this a ploy to to push Vista into our faces and onto our computers? I don't feel this is the case as they have also pulled Vista SP1 from auto installation, but not manual download. I am thinking larger issue than DRMs one which they don't want to explain. But what is it? A backdoor? A severe kernel vulnerability? Who knows, all I have to say is:
*Conspiracy theorists unite!*

I do have it installed and running on my notebook. And my box hasn't been Pwned, yet....
