I figured I'd give my two pence, because I haven't seen much talk going on in my message center.
As with every new layout update, I don't like it first going in. I dislike having the homey feeling I've cultivated with the previous layout being fractured by something new and foreign. I dislike being left to wander around clicking and reacquainting myself, trying to find something familiar with the placement of the art I'm so used to looking at. Initially, it always feels like an intrusion. But after some time I get used to it, find things I like, and end up liking it just fine.
In all probability, the outcome will probably be very similar in
