The screenshot facility is still broken, retaining the orientation (including sideways and upside down, or blank if launching) of the last application use. However, those tiny “x” buttons for closing an app are gone. It’s slide-up again. Thank you, Apple.
Incidentally, battery life has been good (it was good in Beta 2 for me but I hear that iPhone users weren’t as lucky as iPad installs). And responsiveness is pretty good.
