"I'm used to this" does not equal "it's better for everyone," just as "I'm not used to this" doesn't mean "it sucks." And it works in both directions. If you are proficient in lightweight editors (VI, etc.), they are fast, effective, and do most of what you need. But there is a learning curve (am I in edit mode? Did I save my changes?). I certainly understand why people, if exposed to both, side by side, for the first time, would choose a GUI-heavy app. And then to have one with pictures in the menu that might indicate what the commands do along with the text - well, just pamper me, whydon'cha!
For those of us who use keyboard shortcuts, I don't believe those have changed, even if the layout of the menu has (did I miss something there?). Since I'm not looking at the menu when executing my shortcuts, it doesn't really matter if they moved the entry (as long as the keystroke combo didn't change), and if I'm looking for something I don't do frequently, I already didn't know where it was, so whether I'm looking through a list of expandable text menus or an already-expanded ribbon, who cares? I don't get the fuss. I really don't. I'm not criticizing those who don't like it, just saying that I really don't see what's so bad about it, as I don't find there to be any drawbacks.
