- More features isn’t better, it’s worse.
- You can’t make things easier by adding to them.
- Confusion is the ultimate deal-breaker.
- Style matters
- Only features that provide a good user experience will be used.
- Any feature that requires learning will only be adopted by a small fraction of users.
- Unused features are not only useless, they can slow you down and diminish ease of use.
- Users do not want to think about technology: what really counts is what it does for them.
- Forget about the killer feature. Welcome to the age of the killer user-experience.
- Less is difficult, that’s why less is more
