So Nokia then came out with the N97 and it was clear that they did not have the ability anymore to design software or pick a strategy. Their 'app store' switched from MoSH to Ovi and it just simply did not work. All the while Android and iOS were moving very fast. People were very unhappy with the N97 flagship and the rest of the offerings were not very clear. They had dozens of models. E series was supposed to be the business series and N series for "media". It was confusing marketing. From 2009-2012 they were losing double digit marketshare every year. Even strongholds like India and Asia were starting to view Nokia as a company that lost their direction. So yes people did have fond memories of their unbreakable candybar phones but they also associated Nokia with the old days of phones as they could not produce a modern, coherent UI. (until MeeGo where it was too late)
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"
Besides, Nokia had great reputation as a quality brand. Some of their phones were unbreakable. They've lost their reputation since their deal with MS.
