Sad...
What's sad is that this type of list is even needed. While just about every new version of Windows has some sort of compatibility issues, Win8 seems to have more than most. It doesn't bode well for it's success. MS is trying to make it a "must have" for Office 2013, but I don't think that will be enough. I'm curious to see if Win9 gets cranked out quickly the way Win7 followed Vista.
