But Sad !! that old phones, even the flagship Nokia Lumia 900 will not be upgradable to Windows Phone 8m the max update will be till 7.8 version. Anyway, here are the points that I liked Multi processor support !! YES upto 64 CPU's thats coz it is a new kernel rewritten ! displays up to WXGA (1280 x 76 ! yes a bit lacking.. but for now only there are already full HD tests going on Support of data on external storage ( ) so memory card support !! This better, faster hardware will enable new, faster games and other demanding apps which, for the first time, can be written in native code. (Well, it's C/C++, which at least lets developers get out of CLR land.) All this will run on a kernel shared with Windows 8 and Windows RT. In other words: yes, Microsoft has managed to get one platform running on desktops, laptops, tablets and phones, the idea being that apps can be more easily ported from one to the next, promising "games we've never seen before" running on your phones. Online multi player support, Wallet with NFC and many many more features.
