Don't get all worked up over the ribbons in Revit when you see it. First, you can't turn them off, so you might as well deal with them. Second, I think if you'll give them a chance you'll see that a lot of thought was put into them. They "flow" very well. My first reaction to the ribbon when I saw it was predictable: "Oh, great. How do you turn them off?" And then after about an hour of working with them, I decided that I liked them better than the current Design Bar, Pull-down menu, toolbar combination.
Try it, you'll like it.
