As he stated, iOS 8 allows for the addition of widgets to the Notification panel/shade, which is accessible even on the lock screen. While some Android devices allow for the addition of widgets on the lock screen, I believe some devices don't presently have this capability (but don't quote me as I obviously haven't used every Android device ).
Thanks. I'm really intrigued to see how this works when iOS finally comes out. I'm not sure if I like the idea of having them in the notification bar though. It can get cluttered enough as it is without sticking a bunch of widgets in there. However I'll wait and see though.
