The standout there is Apple. Apple builds great products, doesn't do focus groups. They probably do multiple iterations but without large betas, the audience of those iterations is probably very limited.<p>Their releases are not cheap - once you announce a new iPhone, you cannot change the hardware before release so you really need to get it right. The soonest you can update it is a year or so.<p>Most of all,Apple is the canonical example of the 'great man theory'. Apple has several of them - Jobs, Ive and several others whose names generally don't get publicity.<p>Now, this is not to say the original posts points aren't valid - most people don't have the talent or expertise that Apple do. But I just couldn't resist throwing in the obvious counter-example.
