Case in point: The Lumia 1020 is using Nokia's relatively old technology. The Nokia 808 PureView was released in Feb 2012, yet received very little recognition.
All of a sudden, a year later, the Lumia 1020 seems like a "fresh, new" idea. When in fact, Nokia has been marketing this EXACT SAME IDEA for over a year. For better or for worse, the "Windows Phone" brand turns heads. Lumia1020 is sticking with people a lot more than "PureView 808"
