GDC: Microsoft is Betting on AMOLED Screen Display on Windows Phone 7 Series

I got a chance to briefly play with and watch @Loke demonstrate the concept hardware behind Windows Phone 7 Series at the Game Developers Congerence, and it seems that Microsoft is expecting more AMOLED displays and touchscreens. Windows Phone 7 engineers chose black and white backgrounds in the design element with AMOLED considerations--black backgrounds would save power by nature of how AMOLEDs work and the white background is used for emails and text to enhance readability.
