Installed fine, quite a hefty download and I can't find a changelog anywhere, but one obvious thing is that the UI has flipped upside down! The status bar was bottom right but is now top right. I'm not that keen on the arrangement, but I'm sure I'll get used to it. What has gone AWOL is the launcher for windowed apps - anyone have any idea how to get that back? I'm not sure I can live without the windowed Chrome. Also, it's now Android 4.2.2, so you can have widgets on the lock screen on a rotating box affair, which is quite nice.
