There are good things about the ribbon, true, and you're spot on about using horizontal space. I wonder though whether the LibreOffice team have enough solid data about user behavior to make good decisions in what would be a huge redesign - not to mention that, judging by the screenshots, they are already starting to make good use of horizontal space. Also, I'd personally prefer if instead of just permuting UI elements they would adapt some of the really nice ideas that really make things flow better for everyday users. I suppose it's nice to have a bigger Undo button, but wouldn't it be less contentious and more useful in the long term to teach people about Ctrl+Z? In particular, the live previews don't require a permutation of the UI layout, and (during my admittedly limited use) I found it to be the nicest of the changes that people usually associate with the Ribbon.
