My 2/H 2/J install was 3/24. As of now I haven't experienced any problems at all, and am extremely happy with the system. I signed up for the upgrade on the first day, and was really excited. Then I started reading all of the horror stories and thought do I really want to do this. Well I decided to go for it, and like I said... no problems yet. What really tops it off is my Wife really likes it. And that's a big deal!
