I've found there is an interesting corollary to this: a good default configuration is more likely to make your product* successful than a poor default configuration with a lot of customization options.

I'm not saying that products shouldn't strive to be as customizable as possible, just that providing the product with a set of sensible defaults will go a long way in adoption.

* I use product loosely: anything from text-editors, phones, cars, subway sandwiches.
