I don't think this is a good case against Fitts' Law. Remember that Fitts' Law factors in both the distance to a target and the target's size. The placement of menu bars was originally done on screens so small that the distance factor was insignificant compared to the "infinite size" of the screen edge. The problem now isn't Fitts' Law, it is that the distance factor is a greater proportion of the difficulty in hitting a target and the "solution" for menus has not changed accordingly. Personally, I think the distance problem is solved by adjusting the pointing device's tracking speed and acceleration. I've never had any trouble "throwing" my pointer to the edge of a screen on a large monitor. Most mice are perfectly capable of doing rapid acceleration while still allowing precise stops.
