If you read Apple's interface guidelines for Mac OS X, one of the things that is repeated over and over is that they want interface design to be centered on screen instead of the strong, left-aligned nature of the Classic Mac OS.
Apple itself does a reasonably good job of sticking to this design guideline. The dock stays centered on screen. The Apple menubar adornment (no matter how nonfunctional) stays centered onscreen. The drop shadows that the windows and menu cast are made such that it looks like the light source is coming from directly overhead rather than the upper left. Control panel interfaces look very centered.
A centered interface isn't biased against a culture that doesn't have a custom of left-to-right reading (such as Japan or China). It also makes things faster to manipulate from a user interface perspective (Fitt's law I think is the codification of this). Imagine an elevator in a 20 story building. If the elevator is idle, you'd want it to go to the 10 floor so that it'd be quicker to respond to the next user no matter what floor they are on.
So why didn't Apple center the menubar? At first I thought that it would be harder to use. I'm accustomed to just slamming my mouse to the upper left corner to get to the Apple menu, but if the System wide apple menu isn't there any more, that tendency will go away anyway. With different lengths of menubars, finding the consistent menus (like file and edit) won't be in the same place for every app. But since the name of the app, pushes File and Edit around that's not the case for the left aligned menubar either.
It might be that Apple did interface testing with new users and found the left aligned menubar to work better, but if that was the case I'm suprised that they haven't removed the Apple in the center of the menubar
Any thoughts?
