A vaguely related point to this is how the problems with getting details right are related to the simplicity or complexity of the product. The more complex the product, the more details it has, and the harder it is to get all of those details "right". Sometimes it's impossible to get all of them "right" because different market segments have different ideas of what "right" is. That's one of the core reasons I recommend that people start with smaller, simpler products. The easiest way of avoiding getting details wrong is to not have them in the first place. It's much easier to delight a customer with a small simple product - because there are far fewer things for you to foul up :-)
