I think I hate the new ribbon interface as much as Squidward hates Spongebob. I disagree when road worker says "Microsoft doesn't force you to use it". I have yet to find a Microsoft Product, with ribbon toolbars, that gives you the option of using the old tried-and-true interface. These new ribbons seem bulky, cluttered, and overall less functional to me.
That brings up good reason why I love Firefox. It uses a ribbon-like interface by default, but gives users the option to switch back to a "classic" menu bar-based interface. I believe that if Microsoft wants to shake things up on us, they should give us the options to turn off the new interface elements, and keep using the classics. This way, people who like change will get what they want. On the other hand, people like me, who like things just the way they are, will also get what they want. Everybody wins.
Of course, this is all just my opinion.
