What if there was one system that replaced all the rest? Something that could do everything we would ever need to do with a computer, from writing a letter, to the most complicated database configurations. If such a system were available, if it was better than what you use now, and if it were free and open... would you use it? Is it possible to make one single comprehensive system to run your business, personal and all other applications.
It would be the system that would dominate and change the way we use computers, its called Drupal... Never heard of it !
