So I'm curious for those that have upgraded your ipads, how do you cancel a drag operation if you realize you don't want to drop them? I can imagine working my items through app switcher, etc. to get to my destination then decide to cancel prior. Since multi-touch is in full effect, is there a cancel 'x' near the drag files or something? Someone mentioned siri can cancel the drag op but that seems awkward. Do you wiggle them quickly or something?
