It won't sell because it is terrible. the market has already spoken. The UI is beyond unusable. The Zune software is complete garbage...it has failed now for how many years? The proprietary Silverlight platform is horrible...even Microsoft is abandoning it with Windows 8 in favor of industry standard web technologies.
On what planet? Windows Phone OS is on the bottom, below Android, RIM, and even the cancelled Microsoft Windows Mobile. Can you share some sales numbers? Oh yeah, Microsoft won't release any because they are so bad.
Ah, the dreams of a Microsoft fandrone... If you start with a turd,you can polish it however you like, but it is still a turd. How will Nokia's phones be different from the other Microsoft Windows Phone cloners?
Microsoft Windows Phone OS is a complete failure; it does nothing iOS and Android don't already do, and do better. The hardware is terrible (love the forced crappy BING buttons. Guess Microsoft knows no one in the right mind would choose BING over Google so they force the phones to lock to BING), terrible software (Zune failed how many years ago?), and not to mention all the text scrolling off the right of the screen...LOL. UI design 101 fail much?
