My personal UI peeve is alarm clocks.  When I want the sound to stop, I hit the off button as often as I hit snooze, often because the snooze button is smallish and stiff, and I still have to hunt for it amidst the other buttons.<p>What I'd like:<p>When the alarm is going off, <i>any</i> button should snooze.  A later "off" button press (ie, a minute or so) should be what turns off the alarm.  This way, a literal "whack" would silence the alarm, without fear of falling asleep after turning it off.
