Along with the Nokia 800, they also announced the Nokia Lumia 710 which is Windows phone Mango phone too. Nokia 710 is a much more affordable Windows Phone from Nokia. It features the same 1.4 GHz and 3.7″ LCD Clearblack display but this one has a downgraded camera, LCD screen and it is available in white and black colors with swappable covers. I think this phone wants to target the first time smartphone users or the youth.
