The argument is not between adding features and simplicity, between adding capability and usability. The real issue is about design: designing things that have the power required for the job while maintaining understandabili ty, the feeling of control, and the pleasure of accomplishment.
Donald A. NormanI'm not a fan of technology . I'm a fan of pedagogy, of understanding how people learn and the most effective learning methods. But technology enables some exciting changes.

Donald A. NormanToo many companies believe that all they must do is provide a 'neat' technology or some 'cool' product or, sometimes, just good, solid engineering. Nope. All of those are desirable (and solid engineering is a must), but there is much more to a successful product than that: understanding how the product is to be used, design, engineering, positioning, marketing, branding-all matter. It requires designing the Total User Experience.
