Re: Global menu bars?
Having thought more about the article it's clear that he's only concerned with optimising one thing - speed to hit controls. There are more factors to be taken into account such as maximising use of screen space.
E.g. labels on menu bar buttons good because it's a bigger target to hit and therefore faster. In fact the space taken up by the larger buttons might be better used to display more on screen which be useful during all the time that the user isn't thrashing about the screen trying to hit buttons. For most users that's probably most of the time.
