Do you have a reading comprehension problem? The ribbon interface was introduced back in 2007. The ribbon interface, in all of its forms, is an example of bad UI design. It took a dramatic turn for the worse in Office 2013 because the lack of depth and contrast because much worse in that iteration
What is your point of posting here other that blindly defending Microsoft and their poor UI decisions? I have to work with their stuff every day. Do you have a job in a microsoft "shop"? If not, then your opinion is irrelevant.
If you had read more closely, you would have noticed that my main complain of the Ribbon concept is how Microsoft has arbitrarily grouped unrelated functions under the same tab because of space constraints. That was not a problem with the menu. The menu was hierarchical which meant that functions were grouped by groups and sub groups while everything is flattened into a tab now and it can take more time to find what you are looking for.
Microsoft should offer the user the option to use either a ribbon OR the menu and toolbars. They instead decided for the user which is arrogant.
I disagree entirely.
1. The menu was not scalable.
When Microsoft asked their customers what they wanted in the next version of Office, 7 of the top 10 requests were already in the product. Features simply were not discoverable. I was involved with the Vista/Office 2007 betas, and got to know some of the people behind it quite well; their testing showed that the Ribbon had people using a wider array of feature, requiring less mouse clicks.
The menu was just not scalable - for products as packed as those in Office, it just doesn't work. We've all seen the horror pictures:
Obviously those are exaggerations, but the point they're making is that the menus and toolbars don't scale.
2. The Ribbon is arbitrarily grouped because of limited space
The very opposite is true: the Ribbon is very logically grouped, tabs virtually extend the amount of space available (while contextual tabs mean that you aren't overwhelmed with lots of options you can't use right now), and the Ribbon scales very well to fit the amount of space that is available.
The Ribbon is a big change, but it's a change which is overwhelmingly for the better.
