Ok, I am in the New XBOX Experience Preview, and I can now say for sure that all my doubts are gone and I love the new update. I didn't like the look of it first, but it has grown on me and I really like the new dashboard, and I love the mini dashboard that you get when you press the Guide button on your controller. Installing games to the hard drive works great too, and I think that the Avatars are going to be pretty fun to mess about with too.
So yeh, just wanted to say, forget what I said in my last blog post, I can't wait for the release of the NXE now.
