A nice piece from MacRumors, which digs up a 1985 interview with Steve Jobs, including this gem of a quote:

My philosophy is that everything starts with a great product. So, you know, I obviously believed in listening to customers, but customers can’t tell you about the next breakthrough that’s going to happen next year that’s going to change the whole industry. So you have to listen very carefully. But then you have to go and sort of stow away—you have to go hide away with people that really understand the technology, but also really care about the customers, and dream up this next breakthrough.

This is a problem with many industries, not least the majority of the tech world. Most companies provide customers with what they say they want; good companies provided customers with what they actually need, even when they didn’t realise they needed it.
