There is an instant off mode. Pull the plug! Or hold the power button for 10 seconds...hahahaha
With journaled filesystems (both Windows and Mac have had this for awhile now) (if you've ever wondered why chkdsk only runs on *some* power failures) we could probably almost go back to the old way of turning things off at random.. Maybe with some perfection.. You'd still want to save things first, but that has never been any different.
