The pad can be a bit finicky, too -- while it does a fantastic job of recognizing standard Windows multitouch gestures, its own three-finger swipe, used to view the next or previous page of configured buttons, fails to register unless your fingers are lined up perfectly.
When they did they waved their arms around dangerously as if turning their entire bodies would get Mario around the next corner better than just pressing the buttons.
Scrolling through tracks one by one using the tiny buttons can be tedious, but if this were a Shuffle, choosing the next song wouldn't even be an option.
