But Office on the PC wasn't made for a tablet - they intended the ribbon to be used by PC users, and it's terrible. Removing the menus eliminates discover-ability. The common case now when using a recent ribbon-enabled Office application, for me at least, is vaguely recalling a function that I used in a previous version and then hunting around for 2 or 3 minutes through the UI and not finding it. Without doing google searches, I'd never be able to find these features. And each of these feature-hunts adds up to a lot of wasted time.
