Contrary to the Microsoft/Nokia shills, the Nokia Lumia 920 is a flop. Sales are poor.
Damian Dinning, the person who developed the Nokia PureView camera on the Nokia 808, has resigned. Can't blame him, Nokia is now run by Microsoft stooges. Nokia is now the OEM bitch of Microsoft.
No amount of marketing will get people to buy a Windows phone.
Not only is there a lack of apps, getting a Windows phone means you'll have to put up with more of Microsoft's nonsense e.g. Bing, Internet Explorer, Skydrive.
And those tiles on the Windows Phone UI are fugly.
