Problems With New iTunes

I linked to Michael Hyatt's post about this the other day. Apparently this is turning into a big deal. The new version of iTunes seems like it was let into the wild a bit too soon and will cause some damage if you're not prepared. What I had seen earlier was mostly about the problems on Macs but here some info on this problem on PCs from loose wire. I still haven't made the upgrade. Anyone else seeing these problems?
