Proves the articles point even more. Even when all the features are there, people still just wanna get the task out of their hands as quickly as possible and press the bold-button because it takes them one click less than choosing a style, and it is still enough to consider the task complete.

(I know choosing a style is also a one click operation but i'm generalizing)

Styles were available well before 2007. But hardly anyone knew about or used them until the arrival of the ribbon.
