It looks very much coarse-grained. I like the style as it is reminding me about the 90s home computer era.
Unfortunatelly 100 dpis aren't so much for reading ebooks. If I read a textbook will it have the 'real' black and white 300 dpis?
As for solving the color problem. If they would increase the screen to 900dpi it should be 300dpis in color.
