《WHY FEATURES DON'T MATTER ANYMORE: THE NEW LAWS OF DIGITAL TECHNOLOGY》, by Andreas Pfeiffer

1. More features isn't better, it's worse.
   Feature overload is becoming a real issue. The last thing a customer wants is confusion-and what's more confusing than comparing technical specifications, unless you are en expert? Only nerds get a kick out of reading feature lists. (I know - I'm one of them.)
   
   
2. You can't make things easier by adding to them.
   Simplicity means getting something done in a minimum number of simple steps. Practically anything could be simpler - but you don't get there by adding features.
   
   
3. Confusion is the ultimate deal-breaker.
   Confuse a customer, and you lose him. And nothing confuses more easily than complex features and unintuitive functionalities.
   
   
4. Style matters
   Despite what nerds may think, style isn't fluff. On the grand scale of things, style is as important as features-if not more so. Style and elegance can contribute significantly to a good user experience. But style isn't just looks, it's a global approach. Fancy packaging isn't enough.
   
   
5. Only features that provide a good user experience will be used.
   Why did the iPod catch on? Because it was so self-explanatory, and it remains the market leader in terms user experience. Sure, it may be excruciatingly difficult to make devices like digital media players or computers easy to use; but if a product is complex, intimidating or confusing, its chances for success are minimal.
   
   
6. Any feature that requires learning will only be adopted by a small fraction of users.
   Learning new features, even the ones that a user might find interesting or intriguing, is a real issue: nobody has time. Getting consumers to upgrade and adopt new features is one of the biggest problems software publishers face these days.
   
   
7. Unused features are not only useless, they can slow you down and diminish ease of use.
   Over time products become convoluted and increasingly complex to use. The frustration of not finding the one feature you need among a flurry of stuff you don't need, want or even understand, can be considerable. (Ever heard of program called Word?)
   
   
8. Users do not want to think about technology: what really counts is what it does for them.
   The best tool is the one you don't notice. Why do you think pen and paper remain vastly popular for brainstorming? Because you don't have to think about them. Pencils don't crash.
   
   
9. Forget about the killer feature. Welcome to the age of the killer user-experience.
   When technology achieves something desirable without being in your face, when it know how to integrate itself into you wishes and desires without distracting from them, that's when technology lives up to its potential. Unfortunately it's not that simple to get there.
   
   
10. Less is difficult, that's why less is more.
    Let's face it: it's usually harder to do simple things exceedingly well, than to just pile up features. The 80/20 rule applies here too: do well what 80 percent of your users do all the time, and you create a good user experience.
