Do One Thing and do it well
Apple-Style drink the Apple UI kool-aid
The 80/20 Rule fewer features = better experience “At least 80 percent of your users will use a very limited number of features in an application, while less than 20 percent will use all the features.”
UI Elements as Real Objects use what your users know “When possible, model your application’s objects and actions on objects and actions in the real world.”
Multi-Touch Ergonomics give your users the finger “Put most frequently used information near the top, where it is most visible and accessible.” “Provide a fingertip-size target area for all tappable elements.”
