Just received my Libra! Screen doesn't look green as others have said, but I have the white model. The backlight is a bit uneven, it's darker towards the grip side of the eReader, but I'm just thinking of it the way the curve of a book will effect the amount of light on the page
it's not bothering me yet. My Aura One Limited Edition does have a better screen, blacks seem blacker which makes it easier to read with a dim backlight, making it easier in the eyes. The Libra however is much more responsive, ergonomic, and light weight. I'm not sure if I'll be able to adjust to the smaller screen, I like reading a large font. Overall I'm impressed with the Libra considering the price point.
