I wonder if the resizing behaviour was based on data about the amount of time Windows users run programs in any state other than maximized - if they have the program window maximized (or manually dragged to fill the monitor) 99.9% of the time, then they'll almost always see the Ribbon in the same state. Of course, this could lead to user confusion when they move to a new computer with a different resolution (whether upgrading, switching between desktop and laptop, or using a friend's/library/work/etc) and the Ribbon they're used to has been replaced by something completely different...
