I have one of the OLPC XO-1 units in my hands. When the backlight is on, it's still readable under very bright light such as sunlight and will look like the kindle's black & white. When you turn the backlight to zero, it switches to ultra-lowpower hi-res black & white sunlight readable mode. It's pretty neat and something I hope to see in all future devices.
