People who talk trash about the ribbon simply have no idea how average people use their computers. There is immense value for most people by having available functions in your face. If an option is hidden, only the most adventurous users will ever find it. UIs should be functional first and pretty second.
I thought it was pretty well established that average people don't like a huge number of buttons and widgets and colors and icons shoved in their face, particularly if most of them are rarely used. People get confused and overwhelmed easily.
The ribbon is collapsed by default, come on now. It's there for tablet users and I'm sure you noticed the equivalent in Ubuntu is not tablet friendly at all.
Also, nautilus is easily the worst file management utility on any platform currently, most especially the gnome3 variant. Let me know when the Favorites, you know, actually work the way they do in every other file manager (including the gnome2 variant)
I'm used to Marlin, I mean "Files" (in Elementary), and Finder's column view. The Bookmarks that most file managers have make the lack of column browsing a bit more tolerable, but it's still lacking in a great number of ways. But no, not Nautilus's.
