The resizing behavior you outline for the Ribbon is actually a horrible UI design decision for repeat actions, which most are. Example: If a user remembers the "Copy" button as the first big button, or paste as the third little button, etc. Next time you open the window at a different resolution, or you resize, everything changes. Your positional memory of this button is gone. I absolutely hate the Ribbon's design for this. (I don't have windows running, so I'm making this up as an example, but I know it has happened to me before) I prefer apple's "old" menu design over the Ribbon. Albeit seemingly archaic, it's actually a very useful place to store multiple commands in easily readable text that never changes position (especially on a mac, where the menu is always at the top toolbar).
