People say they want simple things, but they don’t. Not always.
Donald Norman argues in Living with Complexity that people really want things that are easy to use, not things that are simple. They want things that are familiar, even if the familiar is complex.
People also want all the features they can handle. If you’re competing with a product that is overwhelmingly complex, then simplicity sells. Otherwise simplicity is perceived as weakness. The more features the better. People may enjoy using simpler products, but they buy complex ones.
It’s hard to remove even vestigial features. If people are in the habit of doing something that is no longer necessary (or never did add much value), you’ll have a lot of work to do to convince them that it’s OK to let go of it.
