I agree with this post for the most part. MS Excel when they switched to the ribbon UI was a huge problem for existing users. I have had certain software running with antiquated UIs, but I keep them in place as users know how to use them. They have enough on their plates that they do not want to have to learn something new and deal with the cognitive overload. If the old way works, they will stick with it, as long as it gets the job done.
