GUI.

Small but meaningful advantage in a manual application:

* Guiding the user to guide a complex machine through a precise sequence of steps in order to achieve a goal, such as reading mail or writing a letter

Automation:

* Natural language recognition, shell scripting

Economy of scale:

* Beautiful formatted text has lost its value due to being ubiquitous, and more and more document processing consists of copying and pasting in an e-mail program
