How Configurable Should a Desktop User Interface be?

The Original Yama writes "In the world of user interface design there are two main schools of thought. The former maintains that the environment must be flexible and configurable enough to adjust to a user's needs. The latter takes the opposite perspective, arguing that many of today's user interfaces have become bloated and overloaded with features, and consequently have become difficult to maintain and use. KDE developer Mosfet shows how the KDE Project has managed to bridge the gap between the 'highly configurable' and 'less is more' camps."
