“Thou shalt make thy program’s purpose and structure clear … for thy creativity is better used in solving problems than in creating beautiful new impediments to understanding.”
~ “The Ten Commandments for C Programmers” by Henry Spencer

How easily can you use your computer? Today, the graphical desktop is our primary way of doing things on our computers; we start there to run web browsers, music programs, video players, and even a command line terminal. If the desktop is too difficult to use, if it takes too many steps to do something, or if the cool functionality of the desktop is hidden so you can’t figure out how to use it, then the computer isn’t very useful to you. So it’s very important for the desktop to get it right. The desktop needs to be very easy for everyone to use.

Whenever we think of how easily you can use a program, we’re really talking about the usability of that program. Developers sometimes discount usability and think of usability as making things look nice instead of adding new, useful features. Other times, developers assume usability is too difficult, something that only experts can do. But usability is a very important part of software development.
