A couple of weeks ago there briefly appeared an App button in the Apps areas that took you to a rather nice exposé of the Carbon UI. It was the best Geek P*rn I could ever ask for. It was only there for a couple of days and was gone when I tried to show someone else on my other HwS. I'm still on S525 and had some wonkiness this morning and the recovery process presented a strange, I've never seen before, ghosted update window with a progress thermometer at the bottom of the screen on top of a program for about half an hour, I tried to keep my hopes down thinking that it was the new UI. But no such luck. Hope S527 does a lot of bug fixing, I have quite a few.
