The problem is that the list is obviously woefully incomplete. While I suppose some of that is Microsoft's responsibility, it seems more than a little farfetched to lay it all on them. Or much of any of it, for that matter.
It's a cinch SP 1 will break some stuff. I am unaware of that sort of major upgrade to anything not breaking some stuff. And that includes the upgrade I just did to my Linux box. (Where IS that penguin, anyway? I'm getting tired of holding this gun.) I would like a much more comprehensive listing, but it is what it is.
